HDFE command for linear model

[Mihails Hazans]

Dear all, is anybody using the reghdfe (or similar) command?
I am able to run the [Poisson] ppmlhdfe, but the similar command for linear models (reghdfe) returns: invalid syntax (error occurred while loading reghdfe.ado).
Any insight would be greatly appreciated.

try updating reghdfe and ftools.

Thank you for the suggestion! Stata says "all files already exist and are up to date".

[Rich Goldstein]

as per the FAQ (if you haven't read it please do so), you need to show us exactly what you typed and exactly what Stata did in response - please post in CODE blocks to make reading it easier

ssc install reghdfe, replace

[Mihails Hazans]

Thank you! Did not work:
ssc install reghdfe, replace
Stata replied:
checking reghdfe consistency and verifying not already installed...
all files already exist and are up to date.

same for ftools?

[George Ford]

provide the specific command that produced the error

[Mihails Hazans]

Yes, same for ftools

[Mihails Hazans]

The command that produced the error:

reghdfe log_rem log_gdppc_ppp_o log_gdppc_ppp_d cstock1000 acq1000 ratio_child_cost if set==1, a(year) vce(cluster pair)

[Mihails Hazans]

Exact same command works with ppmlhdfe

[Mihails Hazans]

I have also tried it without the vce option and with absorb(i.year) instead of a(year).

see if the reghdfe.mata file in the directory with reghdfe.ado
