qua.regressCOP.draw: Draw Quantile Regressions using a Copula by Numerical...

Description Usage Arguments Value Author(s) References See Also Examples

Description

Draw a suite of lines for specified nonexceedance probabilities representing the quantile regression (Nelsen, 2006, pp. 217–218) of either V with respect to U or U with respect to V depending upon an argument setting.

Usage

2
qua.regressCOP.draw(f=seq(0.1, 0.9, by=0.1), fs=0.5, cop=NULL, para=NULL,
                    ploton=TRUE, wrtV=FALSE, col=c(4,2), lwd=c(1,2), lty=1,...)

Arguments

f

Nonexceedance probability F to perform quantile regression at and defaults to a 10-percent-interval sequence. This vectorization of f for this function differs from that in qua.regressCOP and qua.regressCOP2;

fs

A special value of nonexceedance probability to draw with second values to arguments col and lwd and defaults to the median (F = 1/2);

cop

A copula function;

para

Vector of parameters or other data structure, if needed, to pass to the copula;

ploton

A logical to toggle on the plot;

wrtV

If wrtV=FALSE call qua.regressCOP and perform quantile regression of V with respect to U and if wrtV=TRUE call qua.regressCOP2 and perform regression of U with respect to V;

col

A vector of two values for the color of the line to draw, where the first value is used for the f probabilities and the second value is used for the fs probability;

lwd

A vector of two values for the line width of the line to draw, where the first value is used for the f probabilities and the second value is used for the fs probability;

lty

The line type to draw; and

...

Additional arguments to pass.

Value

No values are returned, this function is used for its side effects.
