WebFrom the graph, we see that the cumulative relative frequency of 20 grams of sugar is approximately 0.3, which means that about 30% of the 32 drinks contained at most 20 grams of sugar. 30% of 32 = 9.6, so 9 or 10 of the drinks contained 20 grams of sugar or less, which is the cumulative frequency of 20 grams of sugar. WebCumulative probabilities for an interval are calculated by multiplying the interval survival rates up to that interval. For example, the chances of survival begin in interval one as 6/6, then are 5/6 in interval two, and 4/5 for interval three giving a cumulative survival rate (probability) in interval three of 6/6 × 5/6 × 4/5 = 0.667. biotechnology badWebcumhaz requests that the cumulative hazard function be plotted when used after stcox or streg and requests that the cumulative subhazard function be plotted when used after stcrreg. cif requests that the cumulative incidence function be plotted.
