st: How to drop individuals from sample?

[Dheepan Ratha Krishnan <d.rathakrishnan@student.unimelb.edu.au>]

Hello all,

I am writing my dissertation on happiness adaptation to life events
(such as being fired or getting married) and am looking for a stata
command that will enable me to exclude individuals who have
experienced a particular life event more than once in my dataset. My
reason for doing this is so that I can analyse how individuals adapt
(in terms of happiness scores) to a life event at one particular time
within a specific sample period. For example, within a sample period
of 6 years, if individual A gets fired once and individual B gets
fired twice, how do I omit individual B and others like him from the
sample?
