USING MATHEMATICA ® FOR MULTI-STAGE SELECTION AND OTHER MULTIVARIATE NORMAL CALCULATIONS

The paper discusses the use of the technical computing package Mathematica ® for performing calculations on multivariate normal distributions. An example is given of calculating response to selection using independent culling levels which requires the calculation of the mean and volume of a truncated trivariate normal distribution. The power and flexibility of using Mathematica ® for optimising multi-stage selection is demonstrated and discussed
