Somebody more knowledgeable will probably explain exactly why you can't
use subscripts on the left side like that.
But I can suggest a workaround:
replace y=y[`i'-1] +z[`i'] if _n==`i'

Subject: st: Weights vs subscripts
Hi,
Could any one explain to me why it is OK to write the code in the
following way
gen y=0
foreach i of varlist x {
replace y=y[`i'-1]+ z[`i']
}
but not OK in this way
replace y[`i']=y[`i'-1] +z[`i']
the program always treat the [`i'] on the left side as weights, instead
of subscripts
Thank you,
