Dear statalist,

I am using ivreghdfe and want to know the regression in the first stage. However, stata shows that unable to store frist stage regression, code is as follows. Could someone help? Thanks a lot.

ivreghdfe net_revenue_log if_comment_lag overall_rating_lag (yelp_rating_if_comment_lag = other_bus_rating_if_comment_lag), first absorb(prov_id surveyyear) cl(prov_id)
(MWFE estimator converged in 2 iterations)

Unable to store first-stage regression of yelp_rating_if_comment_lag.


First-stage regressions
-----------------------

Unable to display all first-stage regressions.
There may be insufficient room to store results using -estimates store-,
or names of endogenous regressors may be too long to store the results.
Try dropping one or more estimation results using -estimates drop-,
using the -savefprefix- option, or using shorter variable names.
