Nettet6. okt. 2024 · Keep in mind that the recommended number of training cases where you can be reasonably sure of having a stable fitting for (unregularized) linear classifiers like LDA is n > 3 to 5 p in each class. In your case that would be, say, 200 * 7 * 5 = 7000 cases, so with 500 cases you are more than an order of magnitude below that recommendation.
