WebbDetails. Empirical and, if specified, theoretical distributions are plotted in density and in cdf. For the plot in density, the user can use the arguments histo and demp to specify if he wants the histogram using the function hist, the density plot using the function density, or both (at least one of the two arguments must be put to "TRUE" ). WebbSetup. Consider two random variables X X and Y Y that are independent and identically distributed from a zero-mean Gaussian with variance of 1 1. Now, consider the transformation to two new random variables R R, Θ Θ such that. Also recall that we can transform from R R and Θ Θ to X X and Y Y by the following relationship: X = rcosθ and Y ... reading intent primary school

WebbSo we never really believe our assumed theoretical distributions. The best we can hope for is that the act of sampling from the assumed theoretical distribution adequately mimics the most important features of the process which generated our data.
