Hello All,
In general, I understand that LSDV estimation method is an alternative
way of modeling fixed-effectsin in panel data approach , or it is
equivalent to FE method. But, in STATA, we can specify a LSDV model in two
ways:
(1)with common constant as:
LS y d1 d2 d3 x1 x2 x3 or
(2)we can run it without constant or with non-constant option as:
(for example)LS d1 d2 d3 x1 x2 x3, nonconstant
I got a couple of concerns and questions as follows:
First, which syntax of LSDV given above is appropriate or reliable for
modeling a fixed-effects model? I mean it should be run with constant or
without constant as shown above?
Second, when we run FE model in Stata as:
xtreg y x1 x2 x3, fe
My question is that is this equivalent to LSDV with constant or without
constant?
Thank you in advance.
