/// 

Something like this?

* Example with internal dataset
sysuse auto
logit foreign mpg rep78 trunk weight length

* Get the parameters & define new ones
mat beta =e(b)
mat new = beta

* Count the parameters
local dim=colsof(beta)

* Run a customized loop
forv k=1/`dim' {
mat new[1,`k'] = round(abs(beta[1,`k']))
}

* Check results
mat l new
mat l beta

Hello,

I am not ignoring the signs. I want to transform the parameters
estimates to non-negative integers.
