How to compare two vectors?

[nick3000kimo]

Hello,

I have already working for several hours to run if statement on Eviews 6.
My program is as follow, however, vector cc don't have any signal. Pls someone kindly tell me which line should be corrected. Many many thanks.

vector aa = @columnextract(mvmatrix1,1)
vector bb = @columnextract(mvmatrix1,2)
vector(@obs(aa)) cc
if aa>bb then
vector cc = "Buy"
elseif aa<bb then
vector bb = "Sell"
endif
endif

You'll have to write a loop to go through the elements one at a time.

Code: Select all

vector aa = @columnextract(mvmatrix1,1) vector bb = @columnextract(mvmatrix1,2) vector(@obs(aa)) cc for !i=1 to @rows(cc) if aa(!i)>bb(!) then cc(!i) = 1 endif if aa(!i)<bb(!i) then cc(!i) = 0 endif next
