estimating y and x pairs

Code: Select all

'create a workfile wfcreate q 1990 2010 'create 5 y and 5 x series for %y y1 y2 y3 y4 y5 series {%y}=nrnd for %x x1 x2 x3 x4 x5 series {%x}=nrnd 'run pairwise regressions between each series equation eq_{%y}_{%x}.ls {%y} c {%x} next next

Hello! How do I modify the above code so that only the five equation objects with matching y's and x's are created: eq_y1_x1, eq_y2_x2,eq_y3_x3,eq_y4_x4,eq_y5_x5? Thanks!

Thank you. But what if the series names are xa, xb, xc, xd, xe and ya, yb, yc, yd, ye?

Hello,

You could loop over the common suffix of the x? and y? series, e.g.

Code: Select all

for %s a b c d e equation eq_y{%s}_x{%s}.ls y{%s} c x{%s} next

Similarly named objects let you write terse loops, but can always explicitly list all the names and loop over groups of those elements, e.g.

Code: Select all

for %y %x ya xa yb xb yc xc yd xd ye xe equation eq_{%y}_{%x}.ls {%y} c {%x} next
