How to obtain the following through loops

[Matthew Williams]

Dear all,

Given the following loop:

    foreach y in first_outcome second_outcome {
        eststo `y': reg `y' x1 x2 x3
    }

What I want is to shorten names of storing estimates. For example, I want to have m1 and m2 instead of first_outcome and second_outcome. I have seen something like this but not I was unable to find that thread. Thank you.

 local c = 1 foreach y in first_outcome second_outcome {    eststo m`c': reg `y' x1 x2 x3    local c = `c' + 1 }

 foreach y in m1 m2 {

[Matthew Williams]

local c = 1 foreach y in first_outcome second_outcome { eststo m`c': reg `y' x1 x2 x3 local c = `c' + 1 }

Thank you so much for the quick reply. The code in #2 is exactly what I want. Just a follow-up question, now instead of having m1 and m2, would it be possible to have A and B? Thank you.

sysuse auto, clear
local c = 1  
foreach y in weight trunk {
    local mod : word `c' of `c(ALPHA)'    
    eststo `mod': reg `y' mpg i.rep78    
    local c = `c' + 1  
}

If you have two y, then I wouldn't bother with the loop.

[Matthew Williams]

sysuse auto, clear
local c = 1
foreach y in weight trunk {
local mod : word `c' of `c(ALPHA)'
eststo `mod': reg `y' mpg i.rep78
local c = `c' + 1
}

Thank you so much for the help. Indeed, I have more than two y.

#3 is nonsense here, but journals.sagepub.com/doi/pdf/10.1177/1536867X211063415 includes a review of technique for loops in parallel.
