Hi guys!
is there a command by which I can do gen v1=v2=v3=0 in stata?
A modification which may work ?
Not as far as I'm aware, its invalid syntax.
What is it that you are trying to achieve? If its simply to generate
three variables which are all zero then its simply...
gen v1 = 0
gen v2 = 0
gen v3 = 0
or
forval x = 1/3{
gen v`x' = 0
}
Its not much more typing for either of these, but if you want to
generate more than three variables the later is naturally extensible.
What you will find is that you can do something like....
gen v1 = v2 == v3
..which on the face of it may appear similar to what you originally
wrote, but in actual fact generates v1 as a binary variable taking
values of 0 and 1. If the values of v2 and v3 are equal then the test
for equality is "True" or 1, if they are not equal then the test for
equality is "False" or 0.
