npde.binning: Internal functions used to produce prediction intervals

In npde: Normalised Prediction Distribution Errors for Nonlinear Mixed-Effect Models

Internal functions used to produce prediction intervals

Description

Functions used by plot functions to define the boundaries of the bins on the X-axis

Usage

npde.binning(xvec, plot.opt, verbose = FALSE)

Arguments

xvec	a vector of values for the X-axis of the plot
plot.opt	graphical options
verbose	boolean (defaults to FALSE). If TRUE, a table showing how the binning was performed

Details

These functions are normally not called by the end-user but are now exported for use in the saemix package.

Value

a list with 3 elements, xgrp (the number of the bin associated with each element of xvec), xcent (a named vector containing the mean of the elements of xvec contained in each bin; the name of the bin is the interval), and xgroup (a vector with the group associated to each element of xvec after binning) If verbose is TRUE, a table showing the bins is shown, giving the interval of xvec associated with each bin, the mean value of xvec in each bin, and the number of observations
