Abstract

A family of procedures is given to construct confidence intervals for the heritability of a trait in a mixed linear model. The procedures are applicable for constructing confidence intervals for a ratio of variance components in a mixed linear model having two sources of variation. The resulting intervals are evaluated in terms of expected length. The investigator may select the best confidence interval procedure from the family of procedures based on the interval( s) having short expected length. Confidence intervals for loineye data using bulls from a Red Angus seed stock herd will be presented.

CONFIDENCE INTERVALS FOR HERITABILITY IN A MIXED LINEAR MODEL
