Hello, I have no question about the confusion matrix of a multinomial logistic regression model Here's there is the variable Y with 3 modalities: 1,2,3 Does "Training" mean that JMP automatically does a learning database to learn the model? Indeed when I calculate the total number of observations on my confusion matrix : 311+79+37+98+209+59+48+57+187 = 1085 While my database is 1369 rows And 1085/1369 = 0.79 Does this mean that my confusion matrix is done on a learning dataset that is 80% of my database? And how to know which data has been used to test the ACCURACY of my model on the test dataset? Thank you
