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 3.5   (details) 49/50 ENG   31KB/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.

Water Density and Boiling Temperature   (details) 49/50 ENG   5KB/4KB
ScreenshotCalculates the density of water, given the temperature in Celsius, pressure in Pascals, and whether the water is pure or from the tap. Based on Tanaka's work. As a function of pressure (or altitude and local temperature), it is also possible to get the local boiling temperature of water according to equations of Goff-Gratch (1984) and Arden Buck (1996).
