This is a specific problem emerged in my previous post "Reshape wide".
The data are the following:
What I am trying to do is multiple imputation after having reshaped wide. Having discovered the need to declare xtset, clear before mi-setting in the forum I produced the following code:

What I am trying to do is multiple imputation after having reshaped wide. Having discovered the need to declare xtset, clear before mi-setting in the forum I produced the following code:
Code:
xtset, clear mi set mlong drop data_lancio_molecola inflow outflow internationalproduct molecule mi reshape wide inflow_ratio outflow_ratio nprod avsales avsales_existing avsales_new agefirm tot_sales recalled_dummy_byfirm newmolfirm newmolmarket, i(idfirm) j(Year) mi register imputed inflow_ratio* outflow_ratio* agefirm* mi impute chained (logit) inflow_ratio* (regress) outflow_ratio* (regress) agefirm*(regress) = avsales* tot_sales* newmolfirm* newmolmarket*, add(10) rseed (091107)
Code:
at least one imputation variable required: (method ...) ivar(s)
-- above applies to specification (regress )
mi impute chained: invalid specification;
