coeffs: array (npred x ncomp x nresp) with regression coefficients
ci.coeffs: array (npred x ncomp x nresp x cv) with regression coefficients for computing confidence intervals (e.g. from cross-validation) using Jack-Knifing method
use.mean: logical, tells how to compute standard error for regression coefficients. If TRUE
mean values for ci.coeffs is computed first. If FALSE, values (coefficients computed for global model) are used as mean.
Returns
a list with statistics three arrays: srandard error, t-values and p-values computed for each regression coefficient.
