SpearmanBrown

Perform a Spearman-Brown correction on the provided correlation score.

Compute approach bias scores using different scoring algorithms,
compute bootstrapped and exact split-half reliability estimates,
and compute confidence intervals for individual participant scores.

SpearmanBrown function

<dl><dt>corr</dt>
<dd>To-be-corrected correlation coefficient</dd>
<dt>ntests</dt>
<dd>An integer indicating how many times larger the full test is, for which the corrected correlation coefficient is being computed.
When <code>ntests=2</code>, the formula will compute what the correlation coefficient would be if the test were twice as long.</dd>
<dt>fix.negative</dt>
<dd>Determines how to deal with a negative value. "nullify" sets it to zero,
"bilateral" applies the correction as if it were a positive number, and then sets it to negative. "none" gives the raw value.</dd></dl>
