So, the PLS model is the best model, for explaining our data, compared to the PCR model.Ĭoursera - Online Courses and Specialization Data science In our example, the cross-validation error RMSE obtained with the PLS model is lower than the RMSE obtained using the PCR method. This captures 90% of the variation in the predictors and 75% of the variation in the outcome variable ( medv). The optimal number of principal components included in the PLS model is 9.

The R code is just like that of the PCR method. Additionally, setting ncomp = 5, captures 71% of the information in the outcome variable ( medv), which is good. The summary() function also provides the percentage of variance explained in the predictors (x) and in the outcome ( medv) using different numbers of components.įor example, 80.94% of the variation (or information) contained in the predictors are captured by 5 principal components ( ncomp = 5). Our analysis shows that, choosing five principal components (ncomp = 5) gives the smallest prediction error RMSE. The plot shows the prediction error (RMSE, Chapter made by the model according to the number of principal components incorporated in the model.
