[Gretl-users] A strange script error, and helps on a more efficient script without loops

Hi Allin, I have 2 questions today: 1 As I was trying to create a model using a script, I came across this strange error. Using the wage1 dataset, if I do the following script to create an icon of a model, it gives me an error: gretl version 2022b-git Current session: 2022-05-30 09:04 ? list basic = educ exper tenure female married smsa trade services profocc Replaced list basic ? "basic" <- ols lwage 0 basic --robust The symbol 'ols' is undefined Data error Error executing script: halting If instead, I change the model name to “basic1” for example, there is no problem. In the icon view, I can change the model icon name from “basic1" to “basic” no problem either. 2 How can I change the following script without the 2 loops? <hansl> list full = educ female exper tenure numdep \ nonwhite smsa northcen south west construc ndurman trcommpu trade \ services profserv profocc clerocc servocc matrix fullid = {} # do this the dumb way first loop i=1..nelem(full) fullid |= varnum(varname(full[i])) endloop "model_full" <- ols lwage 0 full --robust matrix pvalues = 2*pvalue(t,$df,abs($coeff) ./ $stderr) matrix id = pvalues .> 0.05 list shortlist = full[1:4] loop i=5..nelem(full) if id[i+1] == 0 shortlist += varnum(varname(full[i])) endif endloop "model_part" <- ols lwage 0 shortlist —robust </hansl>
