In many instances, the probability density function (pdf) of a function of a random variable is obtained from the pdf of the random variable, the inverse function and the derivative of this inverse. The formula tends to be memorized rather than fully understood. This article describes how we ...

We set Ω = P (N)N×Zd where P (N) denotes the q set of probability measure of N: P (N) = q = (q (k))k∈N ∈ [0, 1]N ; q (k) = 1. k∈N d Thus each q ∈ Ωq is a function (t, x) → qt,x = (qt,x (k))k∈N from N × Z to P (N). We ...
Finding Median for a Probability Function:The median is a measure of central tendency, used for samples, frequency distributions and probability distributions also have it. In these cases, it is useful to remember that the median is also the lower 50th perc...
