This method was adopted since all errors in the y-direction are not normally distributed (i.e. the do not follow a Gaussian distribution) for the commonly used least squares regression method for fitting an equation into a set of (x,y)-data points using the Kolmogorov Smirnov test. The ...
A bivariate copula can arise form a bivariate joint cdf. For example, the Gaussian copula is derived from the bivariate Gaussian distribution. Conversely, it can also be used to generate new bivariate probability distributions via (1); seeNelsen (2006)for summaries of methods of constructing copul...

Moreover, being the existing methods specified in the Structural Equation Modeling (SEM) framework, they are still relatively limited when covariates are group-specific. Numerous extensions and applications of GMM and LCMM has been already realized (Lin 2000; Muthén and Asparouhov 2015), but none...
We first define the G class function,a new class of functions,study on its properties,and a method to constuct it by using the relevant knowledge of ordinary differential equation. Then propose two construction methods for establishing the Copula function based on the G class function. Finally,...
We propose to tackle the partial integro-differential equation satisfied by the finite-time ruin probability and develop a new approach to obtain a solution in terms of bivariate Laguerre series as a function of the initial surplus level and the time horizon for a large class of light-tailed ...
