Manipulating data by deleting random set of observations

Postby Occam » Thu Nov 16, 2017 10:37 am

Dear list,

I'm trying to manipulate my data for educational purposes. How to delete a random set of observations of pre-specified size? Deleting cases is straightforward but how about randomly deleting observations?

1st, there has to be real 'justifiable cause' to delete cases!

If to randomly delete then take a random select and delete, but from now on please ..................
