You could multiply each weighted value by, say, 10000, round the number, and then use it to indicate how many multiples of the value you need in your vector. After running a quick loop, you could then run the vector through the fitdist () algorithm.

Probability distribution fitting or simply distribution fitting is the fitting of a probability distribution to a series of data concerning the repeated measurement of a variable phenomenon. The aim of distribution fitting is to predict the probability or to forecast the frequency of occurrence of the magnitude of the phenomenon in a certain interval. There are many probability distributions (see list of probability distributions) of which some can b…
