I see in news articles of number of rapes reported and an estimate for actual number of rape cases. I am interested in knowing about statistical techniques used for making such estimations. Also, are similar techniques used for estimating number of actual COVID cases from identified cases?
I could not find answer to this question on the internet.
Note: I am just interested in the statistical techniques being used and not in politics. My apologies in case this is the wrong place to ask this question.
Thanks in advance!
