Training, validation, and test data sets Data Splitting Methods
For Analytic Solver, partition the data sets into 50% training, 30% validation, and 20% test and use 12345 as the default random seed.When searching for the optimal value of k, search within possible k values from 1 to 10. If the predictor variable values are in thecharacter format, then treat the predictor variable as a categorical variable. Otherwise, treat the predictor variable as a numericalvariable.The Chartered Financial Analyst (CFA) designation is the de facto professional certification
