STAT Linear Regression 3.8e   (details) 49/50 ENG   34 KB / 76 KB
ScreenshotLinear Regression program for P-Var (with or without the constant) of dimension N (if P = then it returns the exact solution) with clear results and indication from which directory-path the variables came from and how each intermediate result and each variable were obtained, t, s, prob-values, beta lower and upper limits, R2 and R2adj, R2mod and R2modAdj when no constant, variation coefficient, full detailed anova with or without constant, correlation matrix and min-max-interval, 1st order partial correlation, half partial, multi-order correlation with Z1... Zk control variables, restriction model test for k independent variables Xi with k < p, including here also t, s, prob-values, variation coefficient, R2... and anova as for full, non-restricted model model, Spearman's rank rho (with or without ties) + rho crit and prob, including rho lower/upper limits.
