6. Simple Regression Tree

Model Training for Simple Regression TreeThis workflow demonstrates how a Simple Regression Tree Model is built and applied to new data.Task Predict the number of mosquitoes found on the basis of species and trap type. Data ReadingRead the new file 'westnilevirus.csv'created after data preprocessing. It contains:1. Trap Type2. Number of Mosquitoes3. Species4.
