A set of mathematical tools, for scientists, engineers and students. Perform symbolic algebra: simplify expressions, differentiate them, integrate them and see how the result was obtained. Factorise polynomials, multiply and divide them, find their GCDs. Solve linear and non-linear equations, minimise an expression. Least squares fit (5 methods). Evaluate math expressions with variables. Complex numbers. Log results. 38 digit precision.

DMFitter ActiveX control allows you to add sophisticated regression analysis tools to your software in a few lines of code. Features include: both linear and nonlinear (Levenberg-Marquardt) least squares curve fitting algorithms, arbitrary user models (defined analytically or by string expressions), event support, weighting. Examples for Excel, VB, Delphi, MSIE, Data Master 2003 and scripting languages are included.

Regression Module Allows the user to investigate relationships between two variables. These finding can be used to predict one variable from the given values of other variables. We cover linear (Spearman`s, t-test, z-transform) and rank (Spearman`s, Kendall`s) correlation, linear regression and conditional means. Standard Probability Distributions Module This module assists in the development of applications that incorporate the Binomial, Poisson
