prior_stats: Some reasonable priors on category means/variances

Description Usage Format

Description

These are based on two sources: Kronrod, Copress, and Feldman (2012, CogSci) used a combination of categorization and discrimination data to estimate underlying mean and variance for /b/ and /p/, assuming a mean of 60ms for /p/ (which is based on Lisker & Abramson, 1964). Goldrick, Vaughn, and Murphy (2013, JASA) analyzed VOTs produced by 12 talkers producing 80 monosyllabic words with word-initial voiced stops (only /b/ analyzed here). Many talkers prevoiced some or most of their /b/s, and these are included separately here.
