*I am using Stata 11 and referring to the paper published on Stata
Journal "Multiple imputation of missing values" by Royston (2004).
*Following the logic of the reported example, I need to impute missing
values for dichothomous varaibles and then to run a quantile
*regression on the complete datasets, considering m=5 copies of the
*These are my 8 varaibles with missing values.
mvis cometivedi1_new cometivedi2_new cometivedi3_new cometivedi4_new
cometivedi5_new cometivedi6_new cometivedi7_new cometivedi8_new using
trial, m(5) genmiss(m_) seed(1981)
micombine qreg quantobuonasalute cometivedi1_new, quantile(.5)
*"micombine" should work with command "qreg" but I get the following
error message: "imputation identifier _mj not found"
*Why does this happen? Any suggestion to impute missing values using a
Multiple Imputation technique able to run a quantile *regression
