[Gretl-users] Omitted variable index

Dear all, I am just using the "omit" command. My initial model has many regressors and the "omit" command with the "--auto=alpha" option reduces the specification substantially. I want to find out the index/position of the variable which is selected as insignificant each round. So lets say I have three regressors. The initial point estimates are: binit = { 0.5, 2, 3.4 } after "omit" the first two regressors are found to be insignificant, and hence the final estimate is, for instance, given by: bfinal = { 3.55 } In this case I would like to have something like a selection vector which takes unity for the omitted variables: select = { 1, 1, 0 } I've got a rather complicated solution in mind but I am wondering whether there is a built-in command which I am not aware of. Thanks in advance! Artur
