Dear Stata list,
I have a seemingly simple problem that I can't seem to figure out.
1) I would like to generate a new variable :
generate newvariable=var1+var2+var3 if dum1=1 and or dum2=1 and or
dum3=1
gen newvariable=(var1+var2+var3) if dum1==1 | dum2==1 | dum3==1
2) If instead I did the following....
generate newvariable=var1+var2+vhttp://

Sendar3 if dum1=1 & dum2=1 & dum3=1
.... I would only capture values for var1, var2 and var3 if ALL the
three dummies simultaneously are 1. is this correct? If so I do
not want this.
This was garbled for some reason. Not sure what happened, but a URL
was posted in the middle. I think I can see one problem, though.
You want newvariable to equal the sum of three variables if any of
the dummy variables = 1, but it looks like you are requiring it to
equal 1 if all of the dummies equal 1. In other words, you are using
the ampersand (&) when you should be using the (|) (see above).
