Reshaping data when one wave is missing

[Castor Comploj]

I want to reshape my data from wide to long.
In the data (SHARE), I have variables myvar1 myvar2 myvar4 myvar5, whereby myvar3 is missing because wave 3 contained different questions (life history questions).

I use the following

reshape long `varlist', i(`ID') j(wave) 

This produces an error in reshaping.

There are two options that could solve this: a) for each selected variable in varlist, generate a missing myvar3, or b) an adaptation to the reshape command as this problem might be more common in other panel studies.
Does anyone have an idea about (b)?

I don't think the missing myvar3 is the reason for your error.

Consider

clear
input byte(ID myvar1 myvar2 myvar4 myvar5)
50   1   2   4   5
51   2   4   8   10
52   3   6   12  15
end

reshape long myvar, i(ID) j(wave)

You can verify that the reshape works just fine.

#2 was correct. My post can be deleted. Apologies.
