cdsscden: Evaluating Conditional PDF, CDF, and Quantiles of Smoothing...

In gss: General Smoothing Splines

Evaluating Conditional PDF, CDF, and Quantiles of Smoothing Spline Conditional Density Estimates

Description

Evaluate conditional pdf, cdf, and quantiles of f(y1|x,y2) for smoothing spline conditional density estimates f(y|x).

Usage

cdsscden(object, y, x, cond, int=NULL)
cpsscden(object, q, x, cond)
cqsscden(object, p, x, cond)

Arguments

object	Object of class "sscden" or "sscden1".
x	Data frame of x values on which conditional density f(y1|x,y2) is to be evaluated.
y	Data frame or vector of y1 points on which conditional density f(y1|x,y2) is to be evaluated.
cond	One row data frame of conditioning variables y2.
q	Vector of points on which cdf is to be evaluated.
p	Vector of probabilities for which quantiles are to be calculated.
int	Vector of normalizing constants.

Details

The arguments x and y are of the same form as the argument newdata in predict.lm, but y in cdsscden can take a vector for 1-D y1.

cpsscden and cqsscden naturally only work for 1-D y1.

Value

cdsscden returns a list object with the following elements.

pdf	Matrix or vector of conditional pdf f(y1|x,y2), with each column corresponding to a distinct x value.
int	Vector of normalizing constants.

cpsscden and cqsscden return a matrix or vector of conditional cdf or quantiles of f(y1|x,y2).

Note

If variables other than factors or numerical vectors are involved in y1, the normalizing constants can not be computed.
