Developing insurance severity claims predictive model using LR

In this sub-section, we will develop a predictive analytics model for predicting accidental loss against the severity claim by clients. We start with importing required libraries:

import org.apache.spark.ml.regression.{LinearRegression, LinearRegressionModel} 
import org.apache.spark.ml.{ Pipeline, PipelineModel } 
import org.apache.spark.ml.evaluation.RegressionEvaluator 
import org.apache.spark.ml.tuning.ParamGridBuilder 
import org.apache.spark.ml.tuning.CrossValidator 
import org.apache.spark.sql._ 
import org.apache.spark.sql.functions._ 
import org.apache.spark.mllib.evaluation.RegressionMetrics 

Then we create an active Spark session as the entry point to the application. In addition, ...
