A probability density function, also known as a bell curve, is a fundamental statistics concept, that describes the likelihood of a continuous random variable taking on a specific value.

The notion of probability density for a random function is not as straight-forward as in finite-dimensional cases. While a probability density function generally does not exist for functional data, we ...

The behaviour of the mean squared errors of estimators of a density and its derivatives proposed by Singh (1977a) is examined. Asymptotic values of mean squared errors at some points, for the normal ...
