I am facing some problems trying to use ivprob user command. NHot matter what
syntax I use, I always receive the r(101) error message "time-series operators
not allowed".
My model is:
dterc - the dependent binary variable
varperc - the endogenous independent variable
vagas - the instrument
varmod - an independent exogenous variable
gdp - an independent exogenous variable
school - an independent exogenous variable
I tried the following sintaxes:
ivprob dterc endog(varperc) iv(vagas) exog(varmod gdp school)
What is wrong?
