Linear discriminant analysis clustering
Nettet3. nov. 2024 · Discriminant analysis is used to predict the probability of belonging to a given class (or category) based on one or multiple predictor variables. It works with continuous and/or categorical predictor variables. Previously, we have described the logistic regression for two-class classification problems, that is when the outcome … Nettet8. nov. 2024 · Overall, cluster analysis (CA) and linear discriminant analysis (LDA) are dimensionality reduction methods.

One of the key assumptions of linear discriminant analysis is that each of the predictor variables have the same variance. An easy way to assure that this assumption is met is to scale each variable such that it has a mean of 0 and a standard deviation of 1. We can quickly do so in R by using the scale () function: … インスタ アンケート 返信 dmNettetComputes linear discriminant analysis (LDA) on classified cluster groups, and determines the goodness of classification for each cluster group.
