Webbsample would seek an equal balance of HIV-positive men and HIV-positive women in a given city, assuming a 1:1 gender ratio in the population. Studies employ purposive rather than quota sampling when the number of participants is more of a target than a steadfast requirement – that is, an approximate rather than a strict quota. WebbTo achieve this in R, we employ the following approach: We assign the number of repetitions, say 10000 10000, to reps and then initialize a matrix fit were the estimates obtained in each sampling iteration shall be stored row-wise. Thus fit has to be a matrix of dimensions reps×2 × 2. In the next step we draw reps random samples of size n ...
