Hi everyone

I would like to create all principal components representing 0.95 of the cumulative proportion of variance explained (PCA).

This is what I have so far where CFP01 is the group name of a number of underlying series.

Code: Select all


%m= "cfp01"	
freeze(table01) {%m}.pcomp(cproport = 0.95, out=table)
!n = @val(@wright(@wleft(table01(6,1),2),1))
For !i = 1 to !n
	%str1 = %str1 + "F" + @str(!i) + " "
next
{%m}.makepcomp(scale=normscore, cpnorm) %str1

The input for the vector names is not a string. The code does not recognise the empty space as a delimiter. Please advise

Thanks

At a quick glance, it looks like there are two issues. First, you have a space before the period in the last line. Second, you need to enclose the %str1 in braces, as in {%str1} so that it's interpreted as a variable name and not as a string.

Thanks, I did get it to work with your advise
