Description
The mathematical model on which analysis is based is a multivariate normal distribution or a combination of multivariate normal distributions. The problems we shall treat have to do with inference concerning para- meters of such distributions, such problems as testing a hypothesis of equality of means, point estimation of correlation coefficients, and decision between several hypotheses of specified distributions.
Although there are statistical problems of multiple measurement that cannot be based on the model of normal distributions and although there are other statistical methods which are applicable to samples from other types of distributions (for example, the multinomial distribution), we shall consider in this book only statistical analysis based on the normal distribu- tion. The main justification for studying methods relating to the normal distribution so intensively is that this mathematical model is suitable for such a large number of cases where multiple measurements are treated.
