EMPIRgridderinv2 {copBasic}

Derivative Inverses of the Grid of the Bivariate Empirical Copula for U with respect to V

Description

Generate a gridded representation of the inverse of the derivatives of the bivariate empirical copula of U with respect to V. This function is the empirical analog to derCOPinv2.

Usage

EMPIRgridderinv2(empgrid=NULL, kumaraswamy=FALSE, dergrid=NULL, ...)

Arguments

empgrid

The grid from EMPIRgrid;

kumaraswamy

A logical to trigger Kumaraswamy smoothing of the conditional quantile function;

dergrid

The results of EMPIRgridder2 and if left NULL then that function is called internally. There is some fragility at times in the quality of the numerical derivative and the author has provided this argument so that the derivative can be computed externally and then fed to this inversion function; and

...

Additional arguments to pass.

Value

The gridded values of the inverse of the derivative of U with respect to V.
