NMath Stats 3.6
.NET regression, anova, clustering, principal component analysis and much more.
NMath Stats contains a data table class with functions for computing descriptive statistics, such as mean, variance, standard deviation, percentile, median, quartiles, geometric mean, harmonic mean, RMS, kurtosis, skewness, and many more; PDF, CDF, inverse CDF, and random variable moments for probability distributions, including normal (Gaussian), Poisson, chi-square, gamma, beta, Student's t, F, binomial, Johnson and negative binomial; Combinatorial functions, such as factorial, log factorial, binomial coefficient, and log binomial; Multiple linear regression; Logistic regression; Basic hypothesis tests, such as z-test, t-test, and F-test, with calculation of p-values, critical values, and confidence intervals; One-way and two-way analysis of variance (ANOVA) and analysis of variance with repeated measures (RANOVA); Partial least squares (PLS) with cross validation and the NIPALS and SIMPLS algorithms; Kruskal-Wallis ranks sum test; Non-negative matrix factorization (NMF); smoothing filters; principal component analysis and clustering. If you are interested in evaluating NMath Stats, we offer a free fully-functional trial version, distributed in binary form only for a 30-day evaluation period. Purchased product includes source code, user documentation, help files and examples.
