I have some questions about the process of doing instrumental variable analysis, and the data interpretation to the result.
I just read the Stata documentation about “ivprobit”.
As an Epidemiologist, the most important thing I want to know is the odds ratio (OR) of an exposure variable(X) to the disease outcome(Y).
When I saw an example in the documentation, it shows “coef.” In the result table.
And my question is: how can I transfer the coefficient into the odds ratio?
I just search for the command in some website, and I got this: "dis exp(Coef.)"
Does it have an alternative way to show the odds ratio directly in the table? Or I just need to type the command that I found, and transfer them into odds ratio by myself?
My second question is: unlike the process in the command “ivregress”, which can report first-stage regression statistics by typing “estat first” or just adding “first” after the ivregress command, how can I get the first-stage regression statistics in “ivprobit”? Does it have some commands to type?
Because the strength of the instrumental variable is also very important when I conduct the analysis by using binary dependent variables (eg. having disease or not)
I just want to say thank you in advance, to people who give me some advice.
Sincerely,
Grace
