On the chance that you actually want the PDF and not a sample - the PDF is the derivative of the CDF.

Maybe use the cubic interpolation instead of linear one? A video on how to calculate PDF and CDF About CampusX:CampusX is an online mentorship program for engineering students. The cdf is defined byJÐBÑ.JÐBÑTÐBÑ JÐBÑ Bgives the accumulated probability up to. 2 Probability,Distribution,Functions Probabilitydistributionfunction (pdf): Function,for,mapping,random,variablesto,real,numbers. It is usually more straightforward to start from the CDF and then to find the PDF by taking the derivative of the CDF. Thus, we should be able to find the CDF and PDF of Y. If X is a continuous random variable and Y g ( X) is a function of X, then Y itself is a random variable. Use a binomial CDF calculator to get the standard deviation, variance, and mean of binomial distribution based on the number of trails you provided. But this should be acceptable, and is inevitable given the data you have. There is another function, the (cdf) which records thecumulative distribution function same probabilities associated with, but in a different way. 4.1.3 Functions of Continuous Random Variables. The interpolation will distort the distribution a little, and so will the fact that the quantiles 1.000e-04 and 9.999e-01 of the original distribution will become the min and max of the generated numbers (the original distribution had some small chance of being outside these limits). The terminological confusion aside, the idea is sound: generating a sample for a custom distribution by transforming a uniform sample by the PPF is a standard approach. I assume that when you write "pdf" you mean "sample" and not an actual probability density function and when you write "matching_discrete_cdf", you mean the "percent point function" (PPF) which is the inverse of CDF.
