"The assumptions of discriminant analysis are the same as those for MANOVA. The analysis is quite sensitive to outliers and the size of the smallest group must be larger than the number of predictor variables. • Multivariate normality: Independent variables are normal for each level of the grouping variable. • Homogeneity of variance/covariance (homoscedasticity): Variances among group variables are … " - Linear discriminant analysis bit by bit

Nettet23. mai 2024 · If the classes are linearly separable, there exists a hyperplane (on the same feature space) to separate them. When there is not, the classes are either non-separable or separated by other types of hyper-surfaces, e.g. if instead of a line, a parabola in 2D feature space can separate the classes, it's said non-linearly separable.

Nettet8.2. Bayes discriminant rule. In the previous section, we implicitly assumed that each subject is equally likely to be from any of the g g populations. This is the simplest case but is an unrealistic assumption in practice. For example, suppose we want to classify photos on the internet as either being a photo of Bill Evans or not Bill Evans.
