Approximating discrete distribution by continuous distribution
Dear all, I have a discrete distribution showing how age is distributed across a population using a certain set of bands: Age <- matrix(c(74045062, 71978405, 122718362, 40489415), ncol=1, dimnames=list(c("<18", "18-34", "35-64", "65+"),c())) Age_dist <- Age/sum(Age) For example I know that 23.94% of all people are between 0-18 years, 23.28% between 18-34 years and so forth. I would like to find a continuous approximation of this discrete distribution in order to estimate the probability that a person is for example 16 years old. Is there...
