    INSTALLATION
 
    WARNING:
    You must have a copy of VBRUN300.DLL in your WINDOWS\SYSTEM directory
    before proceeding with this installation! If you do not have this file,
    download it from HTTP://WWW.HALCYON.COM/CBUTTON/WELCOME and copy it to
    your windows\system directory.
 
    Your diskette contains a SETUP program which will automatically
    install all of the files and libraries on your hard drive.
    To install KURV+:
    1. From the Windows Program Manager select FILE, then select RUN.
    2. Type and Enter A:SETUP (or B:SETUP).
    SETUP will then run. It will expand all of the compressed files on the
    diskette and place them in their correct directories. A new KURV+
    Program Group and its icon will be added to Program Manager.
 
    If the following message should occur during SETUP: "Cannot copy file
    XXXX.XXX" where XXXX.XXX is any file name such as DDEML.DLL, VER.DLL,
    MMSYSTEM.DLL, etc. then, CLOSE ALL PROGRAMS THAT ARE CURRENTLY RUNNING
    BEFORE YOU RUN SETUP (only Program Manager should be running)! Then run
    SETUP.    Should this fail to solve the problem, delete the current
    version of "XXXX.XX" and then run SETUP again.

                                                                   Page 3
    INTRODUCTION
 
    KURV+ has four mathematical modules: a Curve Fitting module, a
    Multiple Linear Regression module, a Fundamental Statistics module,
    and a Graph Builder module. A Statistical Calculator is also provided.
 
    CURVE FITTING MODULE
 
    X,Y data points supplied by the user are processed to determine the
    coefficients for 28 mathematical equations (including third, fourth and
    fifth order polynomials). A built-in data editor allows the user to
    create, edit, or import files for curve fitting. Changes to files, and
    the resulting curve fit changes, can be rapidly made from KURV's master
    control panel. Comparisons of calculated points with actual data points
    are instantly available. The user can also forecast results for points
    beyond the range of the input data. The comparisons and forecasts can
    be displayed as graphs or as tables. All graphs and tables can be
    printed via the Windows printer interface; they can also be copied to
    the Windows clipboard for insertion into other Windows programs. The
    default labels and legends on the graphs can be changed via the new
    label editor on each graph's menu bar.
 
                                                                   Page 4
 
    MULTIPLE LINEAR REGRESSION
 
    In multiple regression, the dependent variable (Y) is predicted in
    terms of 2 or more independent variables or predictors (X1, X2, etc.).
    KURV+ will calculate the least-squares coefficients for linear
    regression with two, three, or four predictors. The general form of the
    equation is: Y = b0 + b1*X1 + b2*X2 + b3*X3 + b4*X4  where Y is the
    dependent variable, X1, X2, X3, X4 are the independent predicators, and
    b0, b1, b2, b3, b4 are the coefficients to be calculated.
 
    For example:
 
    You have priced ready-to-ship 486DX2-66 computers from two companies.
    All else being equal, you have determined the cost as a function of
    MB of RAM and of MB of hard disk storage.

                                                                   Page 5
 
    Company   MB of RAM   MB of hard disk   Total computer cost ($)
    -------   ---------   ---------------   -----------------------
     ALPHA       16            528                  3250
                  8            426                  2750
                  4            214                  2450
     BETA        16            426                  2995
                  8            340                  2495
                  4            120                  2295
 
    You have decided to order a customized 486DX2-66 with 4 MB of RAM and
    528 MB of hard disk. What is the expected cost? The multiple regression
    module in KURV+ will quickly provide the answer--
 
         COST = $1996 + $37.5 * MB of RAM + $1.05 * MB of hard disk.
 
    Thus your customized configuration should cost approximately $2700.
 
    Similar to the curve fitting module, the multiple regression model
    will also allow you to forecast results beyond the range of the input
    data. All forecasts can be displayed as graphs and/or as tables.

 
                                                                   Page 6
    FUNDAMENTAL STATISTICS MODULE
 
    This module calculates the mean, variance, and standard deviation of
    data sets supplied by the user. Data may either be grouped (item value,
    frequency of occurrence) or ungrouped (single column of item values).
    Grouped data may be displayed as a scatter graph.
 
    GRAPH BUILDER MODULE
 
    This module allows you to create your own graphs, independent of the
    other modules. You supply the data and then choose your graph style,
    colors, font style, line style, and grid type. You enter the desired
    graph title, legend, and axis labels. The resulting graph may be
    printed directly or copied to the Windows clipboard.
 
    STATISTICAL CALCULATOR
 
    This calculator can perform the following operations: factorial,
    permutations, combinations, e^x, Y^x, log e, log 10, square root, and
    change sign. Numbers may be stored in a memory register for later
    recall. Memory accumulation is also provided.
 
 
                                                                   Page 7
    GETTING STARTED
 
    Start the Windows Program Manager.
    Double click on the KURV+ Icon.
 
    The opening window will display the contents panel. Chose either the
    Curve Fitting, the Multiple Regression, the Fundamental Statistics, or
    the Graph Builder module.
 
    CURVE FITTING MODULE
 
    Your first step is to enter or import the X,Y points to be curve
    fitted. This is done via the data display/editor on the left side of
    the Master Control Panel. The HELP menu should be read before you
    attempt to use this editor. Please note that the maximum number of data
    pairs that can be processed by KURV+ is 500.
 
    Your second step is to curve fit the displayed data. Select either the
    button labeled FIT TO 25 CURVES or the button labeled FIT TO 3
    POLYNOMIALS.
 
 
                                                                   Page 8
 
    Once the calculations have been performed, you can print the
    coefficients. You can also COMPARE the calculated results with your
    inputs. You can FORECAST Y values for X values between your data input
    points (interpolate) or beyond your last data point (extrapolate).
 
 
    MULTIPLE REGRESSION MODULE
 
    Your first step is to enter or import the X1, X2 (X3, X4 optional) and
    Y data points. This is done via the data display/editor on the left of
    the Master Control Panel. The HELP menu should be read before you
    attempt to use this editor. Please note that the maximum number of data
    rows that can be processed by KURV+ is 500.
 
    Your second step is to process the displayed data. Select the
    button labeled PROCESS DATA. The linear regression equation will be
    displayed in the white text box on the bottom of the panel.
 
 
                                                                   Page 9
 
    Once the calculations have been performed, you can forecast Y values
    for X1, X2, etc. values between your data input points (interpolate) or
    beyond your last data point (extrapolate). To forecast, select the
    FORECAST button. A new control panel will appear. Select either X1, X2
    X3 or X4 for the variable predictor, enter the values for the remaining
    predictors, then enter the minimum and the maximum values for the
    variable predictor. Select either the tabular or the graphical display
    button.
 
    FUNDAMENTAL STATISTICS MODULE
 
    First you must enter or import your data values using the data/display
    editor on the left side of the panel. The HELP menu should be read
    before you attempt to use this editor. Please note that the maximum
    number of data rows that can be processed by KURV+ is 500.
 
 
                                                                   Page 10
 
    If your data is grouped by item value and frequency of occurence,
    select "Grouped" from the option box in the upper right corner of the
    panel, otherwise select "UnGrouped" data (ungrouped data is a single
    column of values). Then select the "Process Data" button. The mean,
    variance, and standard deviation of your data will then be calculated
    and displayed. To view a scatter graph of your data, select the
    "Scatter Graph" button.
 
    GRAPH BUILDER MODULE
 
    To create your own graphs, you must first enter (or import) your X,Y
    data in the data display/editor. Then either select a graph type,
    color, font, line, and grid from the menu bar or accept the defaults
    (black line graph on white, Roman font, thin line, no grid, no Mean).
    If desired, you can also enter a graph title, legend text, X-axis text,
    and Y-axis text. Then select the "Display Graph" button. Your graph
    will be generated in the large white region on your screen. Changes can
    be instantly made and viewed by selecting alternate options from the
    menu bar. To print your graph, select "File" and then "Print". To copy
    your graph to the clipboard, select "Edit" and then "Copy". Please
    refer to the HELP menu for addtional information.


                                                                   Page 11
    STATISTICAL CALCULATOR
 
    To use this calculator as a look-up table, key in a number and then
    select the appropriate function (N!, ln, log, e^x, or sqrt). To
    calculate the permutations or combinations of N things taken R at a
    time, key in N, select either [perm] for permutations or [comb] for
    combinations, key in R, and then select [=]. To raise a number to a
    power, key in the number, select [Y^x], key in the power, and then
    select [=]. To store a number in memory, display the number and then
    select [Sto]. To recall a stored number, select [Rcl]. To add a
    displayed number to the one in memory, select [M+]. This calculator
    uses algebraic notation. Select the HELP button on the calculator for
    further information.
 
                                                                   Page 12
