Hi, dear @FernandoRios

my code is
mmqreg y x ,q(0.25) absorb(v1) nols

then send me error code like this
last estimates not found
r(301);

I do not understand why should have last estimates
Is there a problem with the source code?

if not add abs(v1)
just like
mmqreg y x ,q(0.25) nols
it can send me results

but I really need add abs(v1) to get what I need
hope you can help me

Best wishes,
Can Jin

Try q(25) instead of q(.25)

[Can Jin]

Try q(25) instead of q(.25)

thank you so much, Fernando
but it can not work

and I already solve this problem
just use stata15 SE
this code
mmqreg y x ,q(0.25) absorb(v1) nols
with abs(v1)
it can work in stata 15 SE
but can not work in stata 17 MP
I use stata 17 MP before

I do not know why
but it works

best wishes,
Can
