WOMBAT is a program to facilitate analyses fitting a linear, mixed model via restricted
maximum likelihood (REML).

• It is assumed that traits analysed are continuous and have a multivariate normal distribution. 

• WOMBAT is set up with quantitative genetic analyses in mind, but is readily applicable in other areas. Its main purpose is the estimation of (co)variance components and the resulting genetic parameters. It is particularly suited to analyses of moderately large to large data sets from livestock improvement programmes, fitting relatively simple models.
