a vector, matrix from a vector, and commands to save matrices
corrmat from http://www.stata.com/users/sdriver
corrmat. Create and save correlation or covariance matrices. / Program
by Shannon Driver, StataCorp <[email protected]>. / Creates a correlation
matrix, covariance matrix, or both and optionally / saves them in the
return list and/or matrix dir.
cpcorr from http://fmwww.bc.edu/RePEc/bocode/c
'CPCORR': module for correlations for each row vs each column variable /
cpcorr produces a matrix of correlations for rowvarlist versus /
colvarlist. cpspear does the same for Spearman correlations. This / matrix
may thus be oblong, and need not be square. Both also / allow a single
matpwcorr from http://fmwww.bc.edu/RePEc/bocode/m
'MATPWCORR': module to takes the output from pwcorr and creates the
corresponding matrices / matpwcorr calculates pairwise correlations and
puts the resulting / output into the matrices pv, corr, pv_bonf and
pv_sidak. The / pv_bonf matrix contains the p-values after a Bonferroni /
