Dear R-user, I have two separate independent events. More precisely, i have data of discharged patients from two separate hospitals on each day of a certain year. For each hospital i calculated the non-exceedance probability by using weibull plot position which should be marginal probability of each event. 1-Is it really so............. that non-exceedance probability calculated by using weibull method is the marginal probability of each event.?? 2-If not, which it seems how can i calculate marginal probabilities from non-exceedance probability? thanks in advance Elisa [[alternative HTML version deleted]]
