- KURV+ for WINDOWS, Version 4.0, is a statistical analysis program
- containing three statistical modules and a graph builder module:
-
- CURVE FITTING
- X,Y data points are processed to determine the coefficients for 28
- equations (including 3rd, 4th, and 5th order polynominals). Comparisions of
- calculated points with actual data points are instantly available. The user
- can also forecasts results for points beyond the range of the actual data.
- Both the comparisons and the forecasts can be displayed as line graphs or
- as tables.
-
- MULTIPLE LINEAR REGRESSION
- The dependent variable, Y, is predicted in terms of two, three, or four
- independent variables or predictors (X1, X2, X3, X4). KURV+ calculates the
- least-squares coefficients for a linear equation of the form Y = b0 + b1*X1
- + b2*X2 + b3*X3 + b4*X4. The user may also forecast results using the
- calculated coefficients. These forecasts can be displayed as line graphs or
- as tables.
-
- FUNDAMENTAL STATISTICS
- The mean, variance, and standard deviation are calculated from any sample
- set. The samples may be either grouped or ungrouped. Grouped samples may
- then be displayed as scatter graphs.
-
- GRAPH BUILDER (new to version 4.0)
- Users can create their own graphs, independent of the other modules. Graph
- style, colors, font style, line style, and grid type may be easily changed
- from the options menu. The user can also add a graph title, legend, and
- axis text. The mean for the data may also be displayed.
-
- A data editor is provided in each module to allow the user to either
- manually enter data or to import previously saved data (comma delimited
- and space delimited ASCII files are supported). Graphs and tables
- generated by KURV+ may be directly printed or copied to the Windows
- clipboard.
