8. polynomial regression

Simple Model Training for Polynomial RegressionThis workflow demonstrates how a Polynomial Regression Model is built and applied to new data.Task Predict the number of mosquitoes found on the basis of species and trap type. Data PartitioningCreate two separate partitionsfrom original data set1. training set (80%) 2. test set (20%). Train a ModelThis node builds a polynomialregression model. Most Learnernodes output a PMML model (bluesquare output port). Apply the ModelPredictor nodes apply a specificmodel to a data set and append themodel predictions.
