Select the correct statement regarding the naive Bayes classification
The correct answer is A. it only requires a small amount of training data to estimate the parameters B. Independent variables can be assumed C. only the variances of the variables for each class need to be determined. An advantage of naive Bayes is that it only requires a small amount of training data to estimate the parameters (means and variances of the variables) necessary for classification. Because independent variables are assumed, only the variances of the variables for each class…

Explanation
An advantage of naive Bayes is that it only requires a small amount of training data to estimate the parameters (means and variances of the variables) necessary for classification. Because independent variables are assumed, only the variances of the variables for each class need to be determined and not the entire covariance matrix.
