Dear Allin,

In a WLS estimation when the weight variable contains zeros gretl stops executing saying that "Weight variable is not a dummy but contains zeros"

The same worked perfectly before with the observations weighted 0 being simply dropped 

from the estimation.

Here's a basic code for replication

<hansl>

nulldata 50

series x = normal()

series y = normal()

series w = uniform()

w[1]=0

wls w y x

</hansl>   

Best,

Artur
