Variance is a key statistical measure that represents the degree of spread or dispersion in a dataset. It quantifies how much individual data points differ from the mean (average) value of the dataset ...

We propose a method for reconstructing a probability density function (pdf) from a sample of an n-dimensional probability distribution. The method works by iteratively applying some simple ...

Density functions are nonnegative for all real numbers but greater than zero only at a finite or countably infinite number of points. Density functions are nonnegative for all real numbers and are ...
