Dear all,
If we create a function having a name coinsiding
with the name of a local variable in a package,
then calling a package function would print

In regard to function function_name (package package_nam):
Warning: 'some_name' shadows a function of the same name

include lp-mfx.gfn

function void den(scalar x)
   eval floor(x)
end function

open keane.gdt -q
smpl (year==87) --restrict
logit status 0 educ exper expersq black --multinomial -q
bundle b = mlogit_mfx(status, $xlist, $coeff, $vcv, $sample)

The cause:
The package function mlogit_pj() has
a local variable named "den"
