Abstract
 Functional data analysis is used to develop statistical approaches to the data sets that are functional and continuous es
sentially, and because these functions belong to the spaces with infinite dimensional, using conventional methods in classical
 statistics for analyzing such data sets is challenging. The most popular technique for statistical data analysis is the functional
 principal components approach, which is an important tool for dimensional reduction. In this research, using the method of
 functional principal component regression based on the second derivative penalty, ridge and lasso, the analysis of Canadian
 climate and spectrometric data sets is proceed. To do this, to obtain the optimum values of the penalized parameter in pro
posed methods, the generalized cross validation, which is a valid and efficient criterion, is applied.
