Multivariate Dependence with Copulas

Classes (S4) of commonly used elliptical, Archimedean, extreme-value and other copula families, as well as their rotations, mixtures and asymmetrizations. Nested Archimedean copulas, related tools and special functions. Methods for density, distribution, random number generation, bivariate dependence measures, Rosenblatt transform, Kendall distribution function, perspective and contour plots. Fitting of copula models with potentially partly fixed parameters, including standard errors. Serial independence tests, copula specification tests (independence, exchangeability, radial symmetry, extreme-value dependence, goodness-of-fit) and model selection based on cross-validation. Empirical copula, smoothed versions, and non-parametric estimators of the Pickands dependence function.

README

archmCPdf.m: Mathematica code that generates expressions of Archimedean copula
             cdf, pdf, and genfun derivatives; the maximum dimension for Frank
             is determined to be 4, otherwise, the system run out of memory.
             In particular, derPdfWrtPar is the toughest one to get.

evcopula.nb: Mathematica notebook that generates expressions of extreme value
             copula cdf, pdf, and deriv1cdf

exprPrep.R: R code that reads the expression files and generate R objects
            into files ../../R/*Expr.R .

	    The input of algr2dump is a copula which has cdf and pdf expressions
            in exprdist. It generates these files: claytonExpr.R,
	    gumbelExpr.R, frankExpr.R, amhExpr.R, plackettExpr.R,
	    galambosExpr.R, huslerReissExpr.R.


getDerExpr.m: Abandoned Mathematica code that generates derivative expressions.
              Reason of abandoning: after reading pdf expressions back in,
              they are not exactly the same as before. Why?
