cond.mode: Conditional mode

In fda.usc: Functional Data Analysis and Utilities for Statistical Computing

Conditional mode

Description

Computes the mode for conditional distribution function.

Usage

cond.mode(Fc, method = "monoH.FC", draw = TRUE)

Arguments

Fc	Object estimated by cond.F function.
method	Specifies the type of spline to be used. Possible values are "diff", "fmm", "natural", "periodic" and "monoH.FC".
draw	=TRUE, plots the conditional distribution and density function.

Details

The conditional mode is calculated as the maximum argument of the derivative of the conditional distribution function (density function f).

Value

Return the mode for conditional distribution function.

• mode.cond: Conditional mode.

• x: A grid of length n where the conditional density function is evaluated.

• f: The conditional density function evaluated at x.
