Websimu.Clayton Simulating data from the Clayton copula Description n pairs of (U,V) are generated from the Clayton copula. n paris of (X,Y) are generated from the cor-responding bivariate survival model with the Weibull marginal distributions. The default parameters (scale1=scale2=shape1=shape2=1) give the unit exponential distributions. Usage WebThis article studies a new family of bivariate copulas constructed using the unit-Lomax distortion derived from a transformation of the non-negative Lomax random variable into a variable whose support is the unit interval. Existing copulas play the role of the base copulas that are distorted into new families of copulas with additional parameters, …
