[Gretl-users] Principal Components Analysis Misbehavior

Dear Gretl Team, I think I found a possible error using the "pca" command. Please take a look at the following code: <hansl> open australia.gdt pca PAU PUS E --save-all # It saves all the components clear open australia.gdt pca PAU PUS E --save[1] # It saves only the first component clear open australia.gdt pca PAU PUS E --save[2] # It was supposed to save only the second # component, but Gretl saves only the first clear open australia.gdt pca PAU PUS E --save[3] # It was supposed to save only the third # component, but Gretl saves only the first <hansl> According to the Gretl's Help, in respect to the option "--save[=n]": "If you provide a value for n with this option then the most important n components are saved." Additionally, inside a BIG loop I am building, the order of the options "--save[1]" and "--quiet" is changing the behavior of Gretl. Using the format "pca ... --save[1] --quiet" doesn't suppress the printing of the PCA results. To suppress, I need to use "pca ... --quiet --save[1]". Best regards, Henrique Andrade* *
