Which of these statements are valid interpretations of the PCA analysis of the smoothed precipitation data for the state of Washington?
a. Precipitation generally happens in the summer season (June -August)
b. Precipitation generally occurs in the winter season (December -February)
c. The second eigenvector for this data represents the deviation inthe yearly rainfall for a particular station from the mean rainfallacross all stations in Washington and all years in the dataset.
d. A positive value for the coefficient associated with the secondeigenvector implies that the rainfall was heavier than thestatewide average across the entire dataset
e. A positive value for the coe"cient associated with the secondeigenvector implies that the peak of the rainfall is in Decemberas opposed to February.
