Discussing probability and statistics needed by physicists and engineers, they cover random phenomena, probability, random variables, expected values, commonly used discrete distributions, commonly used density functions, joint distributions, some multivariate distributions, a collection of random variables, sampling distributions, estimation, interval estimation, tests of statistical hypotheses, model building and regression, and designing experiments and analyzing variance.
The kernel density function-based method is a positivity-preserving representation and can be regarded as the development of parameter-fitting method, which approximates the PSD by a superposition of weighted kernel density functions [10].
