The concept of the cumulative distribution function makes an explicit appearance in statistical analysis in two (similar) ways. Cumulative frequency analysis is the analysis of the frequency of occurrence of values of a phenomenon less than a reference value. The empirical distribution function is a formal direct estimate of the cumulative distribution function for which simple statistical properties can be derived and which can form the basis of various statistical hypothesi… WebIn case of BinomialCDF, I tried solving this problem manually. Because P (X<=4), therefore, I calculated P (X=1)+ P (X=2)+P (X=3)+P (X=4) = 0.89537 which does not match with your result. Then I calculated P (X=1)+ P (X=2)+P (X=3)+P (X=4)+P (X=5) = 0.94197 which also does not match with your result. Am I doing it wrong?
