Multinormal distribution

In general, the mathematics of the normal distribution are of little concern to ecologists using unidimensional statistical methods. In the best case, data are normalized (Section 1.5) before being subjected to tests that are based on parametric hypotheses. It must be remembered that all parametric tests require the data to follow a specific distribution, most often the normal distribution. When the data do not obey this

Table 4.5 Main properties of the coefficient of linear correlation. Some of these properties are discussed in later sections.
