KURV+ for WINDOWS
KURV+ is a statistical analysis program with 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.
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.
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.

The price for the licensed version of KURV+ is $20 (U.S. Funds).
