Realized heritability of binary behavioral responses

The distribution of a sample of binary responses, such as SCORE = the number of positive responses of m trials, can be modeled by the beta-binomial compound density. The heritability of SCORE is estimated following the method detailed by W.G. Hill ((1972). Biometrics 27:293-311), but the formula for...

Description
Summary:The distribution of a sample of binary responses, such as SCORE = the number of positive responses of m trials, can be modeled by the beta-binomial compound density. The heritability of SCORE is estimated following the method detailed by W.G. Hill ((1972). Biometrics 27:293-311), but the formula for the standard error is changed. The beta mixing density for p(response) allows for a variety of shapes for the distribution of individual p(response) values about the population mean. An example is provided in which SCORE has a low heritability but the response to divergent selection can be seen clearly in the change in the shape of the distribution of individual p(response) values. These changes in shape can be diagnosed from sample estimates of the beta shape parameters, since these determine the mean, mode, and variance.
