last estimates not found r(301) when adding absorb() about ivreghdfe

[JUJU-Boy]

I have the same problem, because when I execute net install ftools command, it shows host not found, so I use “ssc install” to install, the result of the two installation methods should be the same. But it still shows:
ivreghdfe price weight (length=gear), absorb(rep78, tol(1e-6))
last estimates not found

Hi @JUJU-Boy

SSC often has the older version so it''s best to install from Github.

I just tested the instructions listed here and they work:

cap ado uninstall ftools
net install ftools, from(https://github.com/sergiocorreia/ftools/raw/master/src/)

Best,
S

Try re-installing all the required packages from GitHub, worked for me.

* Install ftools (remove program if it existed previously)
cap ado uninstall ftools
net install ftools, from("https://raw.githubusercontent.com/sergiocorreia/ftools/master/src/")

* Install reghdfe
cap ado uninstall reghdfe
net install reghdfe, from("https://raw.githubusercontent.com/sergiocorreia/reghdfe/master/src/")

* Install ivreg2, the core package
cap ado uninstall ivreg2
ssc install ivreg2

* Finally, install this package
cap ado uninstall ivreghdfe
net install ivreghdfe, from(https://raw.githubusercontent.com/sergiocorreia/ivreghdfe/master/src/)

My guess is that the ivreghdfe instruction makes an error when calling the external command ivreg2. The error may be that the parameters related to the model results are wrong when passing, or more seriously, almost no other external commands are called. Therefore, it is recommended to internalize the external instructions and make the ivreghdfe instruction more independent. This can be done without calling an external command.
