X can take an infinite number of values on an interval, the probability that a continuous R.V. X takes any single given value is The probability distribution (frequency of occurrence) of an individual variable, X, may be obtained via the pdfx function. Given two variables X and Y, the bivariate joint probability distribution returned by the pdfxy function indicates the probability of occurrence defined in terms of both X and Y.. Generally, the larger the array(s) the smoother the derived PDF.
