Please rank these four classification models from the most flexible model to the least flexible model: (assume that the dataset contains 5 variables, but a model doesn't have to use all variables. ) Logistic regression with 1 variable Logistic regression with 5 variables KNN with K=1 using all 5 variables KNN with K=3 using all 5 variables - Y Logistic regression with 1 variable Logistic regression with 5 variables KNN with K=1 using all 5 variables - v KNN with K=3 using all 5 variables
