Jan 10 at 13:24 comment added HelloGoodbye When it comes to modelling of the probability density function (PDF), you need to use the Dirac delta function in order to get a positive probability mass at zero (if you just try to define the PDF as an ordinary function f(x) with a specific value f(0) = y at zero, the integral of f will be independent of y and the limit of the integral from -a to a over f where a approaches 0 will be 0, so the probability mass at zero will be 0).
