Function that transforms a non positive definite symmetric matrix to a positive definite.Function that transforms a non positive definite symmetric matrix to positive definite symmetric matrix -i.e. invertible-.One particular case could be the inversion of a covariance matrix. The...

These routines are the improved calculation routines for Mathieu functions with positive parameters based on Ben Barrowes' direct translation, performed using f2matlab, of the original FORTRAN-77 implementation of "Computation of Special Functions."The package includes the following...

This function generate random variables distributed according to a truncated normal distribution (or, by a translation, to a normal distribution with positive support). This kind of problem is especially interesting for generating variables with MCMC methods.We use a mixed accept-reject...

Cronbach's dodA (alpha) has an important use as a measure of the reliability of a psychometric instrument. It indicates the extent to which a set of test items can be treated as measuring a single latent variable. It was first named as alpha by Cronbach (1951), although an earlier version is the...

For fixed integers a and b with D = a^2 + 4*b positive, the sequence U_n = GeneralizedFibonacci(n,a,b) satisfies the recurrence U_n = a U_{n-1} + b U_{n-2} with initial conditions U_0 = 0 and U_1 = 1. If a=b=1, this is the Fibonacci sequence.
