Hello all,
I've recently been examining some data and, with the help of an expert in the field, have determined that some of our biological assays obtained invalid responses. It is appropriate to omit these data and impute them? If so, does this make the data MNAR? If it can't be done, are there alternatives to simply omitting the data from analyses (as these are single instances in a before and after repeated measures)?
Many thanks,
Jason
