I am estimating a model by passing a list of variables and extra items in bundle to a user defined function I would like to be able to print out results that include the effective sample period in the same way the OLS procedure does I.e. smpl 1995:4 2012:4 list xlist= x1 x2 x3 x4 ols y const xlist prints ==> Model 1: OLS, using observations 1985:1-2012:4 (T = 112) Dependent variable: y ... plus results ... My function would be defined as function bundle bestimate(list xlist, bundle bmodel) ... end function In my case it is most convenient to put all variables in xlist and pull out the first as the dependent variable. I can figure everything I need except how to capture the smpl dates for a printout. Any suggestions? I would especially like to be able to show the effective dates for any cases where lags create missing observations or the data ends before the last smpl date.
