ReineckeWells

These data represent porosity and permeability data from laboratory analysis for the Reinecke Oil Field, Horseshoe Atoll, Texas as used for the outstanding article by Saller and Dickson (2011). Information pertaining to depth and well number have been removed out of curtosy to Dr. Art Saller, who shared a CSV file with the author of the <pkg>copBasic</pkg> package sometime in 2011.

This package implements extensive, but select, functions
        for copula computations and is used by several other packages
        by the author. This particular package provides the lower,
        upper, product, "PSP," and Plackett copulas. Plackett parameter
        estimation is provided. Expressions available for an arbitrary
        copula include the diagonal of a copula, the survival copula,
        the dual of a copula, and co-copula. Levels curves, such as for
        drawing, are available, through inverses of copulas. Sections
        (horizontal and vertical) and derivatives of these sections are
        supported. The numerical derivative for the derivative of a
        copula is provided as are inverses of these the numerical
        derivatives. Inverses of copula derivatives are important for
        random variate generation, which is provided using the
        conditional distribution method and the derivative of a copula.
        Composition of a single copula for two external parameters,
        composition of two copulas through use of two external
        parameters, and the composition of two copulas through the use
        of four external parameters is provided.  Composite copula
        random variates can be generated---compositions generally yield
        asymmetric copulas. A data set is provided that contains darts
        thrown at the L-comoment space of a Plackett-Plackett
        composited copula; these data might be used for experimental
        copula estimation by the method of L-comoments. Measures of
        association through concordance include Kendall Tau, Spearman
        Rho, Gini Gamma, and Blomqvist Beta. Schweizer-Wolff Sigma is
        provided as a measure of dependency in contrast to the
        concordance measures. Upper- and lower-tail dependence is
        computed by numerical limit convergence. Whether a copula is
        left-tail decreasing or right-tail increasing also is provided.
        Quantile and median regression for V with respect to U and U
        with respect to V is available. Empirical copulas (EC) are
        supported and the computation of a data frame for each sample
        value also is provided. ECs are heavily dependent on a simple
        grid or matrix structure for which generation capability is
        provided. The derivatives of the EC grid, which are the
        conditional CDFs of copula sections, are computable. Also, the
        inverses of the derivatives, which are the conditional QDFs of
        copula sections are computable. Median and quantile regression
        of an EC is supported. Lastly, support for EC simulation of V
        conditional on U is provided.
