egen anycount

[Tracy Lam]

I have five variables that all take on values 0, 1, or 2. I want to create a new variable that equals 1 if the five variables only take on values 0 or 1, excluding 2. What would that look like?

[Nick Cox]

egen wanted = rowmax(v1 v2 v3 v4 v5) 
replace wanted = wanted <= 1

[Nick Cox]

gen wanted = max(v1, v2, v3, v4, v5) <= 1

is another way to do it.
