What Is A Probability Density Function? A probability density function, also known as a bell curve, is a fundamental statistics concept, that describes the likelihood of a continuous random variable ...

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 ...

This paper develops a new scheme for improving an approximation method of a probability density function, which is inspired by the idea in the Hilbert space projection theorem. Moreover, we apply ...

One approach to the waiting-time problem is through the integral equation, whose solution is the cumulative probability function-the method derived by Lindley. The equation is of the type for which a ...

Let F be the cumulative distribution function (c.d.f.) of a non-negative random variable with the probability density function (p.d.f.) f and the mean residual life (m.r.l.) function m(t). It is ...
