Help with Dummy Variables

[Mej12]

Hi,

I have a dummy variable and i only want to include the observations that are '0' and leave out the '1' observations. I sorted the variable so that all the 0s will come first. I then tried to change the number of observations so that it will only include the '0's, but this came up with an error. Could someone please help with this? How can I ensure I'm only including the '0' observations in my model?

Hi, thank you for replying. I'm not too sure what you mean. Could you clarify your earlier comment?

Type in that command and only observations where variable equals zero will be included.
