WebMar 27, 2024 · The values of A are my output values, and the values of B are the probabilities of each value in A. So, prob(A(i,j)) = B(i,j). I expect there to be many repetitions in A (not each output is unique) so I want to find two vectors, one which tells me the unique values of A and the other which tells me the probability of each of those unique values. WebJun 9, 2024 · Notice that all the probabilities are greater than zero and that they sum to one. Probability mass functions A probability mass function (PMF) is a mathematical function that describes a discrete probability distribution. It gives the probability of every possible value of a variable.
