Hey guys,

I'm conducting a study that analyses the antecedents of corporate divestitures based on a case control design. The sampling is done based on the dependent variable. Cases are firms that engaged in a divestiture over a certain period of time and controls are firms that did not. My sample was designed as such: for each case firm, a control firm was matched, leaving me with a ratio of case to control firms of 1:1.
I found studies that followed a similar approach and subsequently weighted the ratio of cases to control firms to minimise biases in the model parameters. For example the initial sample ratio was 1:1 and they ended up with a ratio of 1:5 using the stata weight command.
I am a bit uncertain on which weight command to use and how to create a variable that incorporates the weight of e.g. 1:5.

I would really appreciate your support.

Thank you very much

Daniel
