Description of Statistics for MtxVec :
The Statistics for MtxVec introduces basic and more advanced routines for statistical analysis. Since it's a MtxVec Add-On package it requires the latest MtxVec version installed on your machine.Statistics for MtxVec demonstrates how easy, fast and performance efficient it is to build advanced numerical algorithms with MtxVec. Many of the essential statistical routines presented in this package were not available to Delphi developers at all - until now. The end result is Statistics for MtxVec package with almost 200 different routines(not counting overloads). The package is build without requiring any additional dlls and full source is available in Delphi Pascal.FeaturesA comlete list of all available routines with examples is available here. Bellow are some of them:Distributions: Different disctributions (PDF, CDF and inverse CDF for 19 distrubutions), random number generators, parameter estimate.Descriptive statistics: Histograms, ogives, cumulative sum, n-th moments, percentile, range, IQR, mean, median, ...Principal component analysis (PCA): PCA by using covariance/correlation matrix, PCA residuals, Bartlett test for dimensionality, Z-Scores.Hypothesys testing: Nonparametric tests (Sign test, Wilcoxon Signed Rank test), parametric tests (one-sample t-test, two-sample paired/unpaired t-test, Z-Test, Chi-Squared test, F-Test)Regression models: linear (weighted, unweighted), multiple linear (weighted, unweighted), logistic regression,ridge regression, non-linear regression (using the BFGS, Marquardt, Conjugate gradient or Simplex method), one-way and two-way ANOVA.OPTIONAL INSTALL : Statistical charts (precondition - installed TeeChart v5 PRO or above): Probabilities plot (Normal, Weibull, QQ), variable control charts ( X,R, S and EWMA), attribute control charts (P, NP, U and C) + all major statistical chart types, supported by TeeChart (error, barr, error bar, pie, box, scatter, scatter 3D, histogram, ...) Ready-to-use components: TMtxANOVA (encapsulates ANOVA routines), TMtxMulLinReg (encapsulates multiple linear regression routines), TMtxNonLinReg (encapsulates nonlinear regression routines), TMtxPCA (encapsulates PCA routines), TMtxHypothesisTest (encapsulates hypothesis testing routines).A single pass all-in-one installer is also available: (14 Mb):http://downloads.dewresearch.com/Public_Builds/Lab_Studio/LabStudioTrialDelphi.EXE
