regcoeffs.getStats function

<dl><dt>coeffs</dt>
<dd>array (npred x ncomp x nresp) with regression coefficients</dd>
<dt>ci.coeffs</dt>
<dd>array (npred x ncomp x nresp x cv) with regression coefficients for
computing confidence intervals (e.g. from cross-validation) using Jack-Knifing method</dd>
<dt>use.mean</dt>
<dd>logical, tells how to compute standard error for regression coefficients. If <code>TRUE</code>
mean values for ci.coeffs is computed first. If <code>FALSE</code>, <code>values</code> (coefficients
computed for global model) are used as mean.</dd></dl>
