Storing one regression coefficient out of many others in "reghdfe"

[Kedar Kelkar]

I have a fixed effects regression with many controls.

reghdfe pm p_diff l1.pm dd ddXpay rnd firm_volatility industry_volatility ind_mkt ind_tang s_gr net_ppe, absorb(co_code)

I want to store the coefficient of ddXpay only.

Thanks

like the following?

local b4=_b[ddXpay]
dis `b4'

It all depends on how you want to store it
