Hi all,
Thanks again for additional comments. I've incorporated these, so I think this is almost sorted. Three points that I'd like to get feedback on are:
-
Is it possible to count the number of times that a respondent uses a particular answer? For example, I'd like to count how many times a respondent answers 'don't know' or 'didn't answer' for the entire survey (and add this at the end)
-
For those two answers, I've put an associated value of 0. Usually, I'd prefer to add something like 99, so it's clear that this is not a response. However this would screw up the PPI calculation, even if used on only one question. Using '0' also errs on the side of caution - assuming that households are poorer than they are if the answer to this question was known. There's a lot of discussion on the PPI forum around this, and the difficulties of missing questions, so grateful for other thoughts/comments.

How useful is it to calculate PPI look-up values in the survey itself? I've added a calculate function for the PPI number, which will be hidden, to make it easier when analysing data (avoiding having to sum/calculate in Stata etc). However, would it be useful to also calculate associated probabilities of poverty for each poverty line? My instinctive feeling is that this wouldn't be that useful, and may add to the complexity of administering the survey (as a separate csv would need to be included with the survey tool) and may not be useful for analysis (as different poverty lines are of interest depending on the analysis being completed).
Thanks all!
