A probability density function (PDF) describes the likelihood of different outcomes for a continuous random variable.

Probability density function (PDF) Original research An iterative copula method for probability density estimation This paper puts forward a technique with which to reconstruct a probability density ...

A class of probability density estimates can be obtained by penalizing the likelihood by a functional which depends on the roughness of the logarithm of the density. The limiting case of the estimates ...

An unknown density function f (x), its derivatives, and its characteristic function are estimated by means of Hermite functions {h j}. The estimates use the partial sums of series of Hermite functions ...
