M.Power 6   (details) 49/50 ENG   3KB/2KB
For all or most real or complex matrices M, calculates, by diagonalization or by "forced" pseudo approximated diagonalization, one possible exact or one "forced" approximated real (or complex) matrix for M^x (x=real, fraction or integers, positive or negative). Use Original Matrix in stack level 2, x power or xth root in level 1, and run the program.

Polynomial Transformation into Real Array 2g/3a   (details) 49/50 ENG   7KB/1-2KB
ScreenshotObtains the real coefficients from a polynomial with real coefficients: f(an × x^n +...+a0) —> [an... a0], an... a0 real. The variable of the polynomial may be defined in the current directory, or not. The program will also detect incorrect similar variable names and give a corresponding message warning (as only 1 variable is allowed).

STAT Inv as User Key   (details) 49/50 ENG   3KB/1KB
To make it easier to do the inverse functions of UTPC, UTPF, UTPN, UTPTN, without having to write a "root-solver" from scratch, this program assigns user key functions to do Inv.UTPC, Inv.UTPF, Inv.UTPN, and Inv.UTPT: LS-User C (C for Chi), LS-User F (C for Fisher), LS-User N (C for Normal), and LS-User T (C for sTudent).

STAT Linear Regression 3.8e   (details) 49/50 ENG   34KB/76KB
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. All stats calculated for any chosen value of alpha (set to 5% by default or if you incidentally erase it), even for Spearman's rho H0-prob and rho crit when N < 11.
