Nettet30. okt. 2024 · Step 3: Scale the Data. 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: … Nettet线性判别分析(linear discriminant analysis，LDA)是对费舍尔的线性鉴别方法的归纳，这种方法使用统计学，模式识别和机器学习方法，试图找到两类物体或事件的特征的一个线性组合，以能够特征化或区分它们。所得的组合可用来作为一个线性分类器，或者，更常见的是，为后续的分类做降维处理。
