compCDF {mixtools}R Documentation

Plot the Component CDF

Description

Plot the components' CDF via the posterior probabilities.

Usage

compCDF(x, weights)

Arguments

x A matrix containing the raw data. Rows are subjects and columns are repeated measurements.
weights The weights to compute the empirical CDF; however, most of time they are the posterior probabilities.

Value

compCDF returns an object which is a list with components:

result The component means and standard deviations for a k-component mixture.
plot The plotted component CDF.

Examples

## The sulfur content of the coal seams in Texas

A<-c(1.51, 1.92, 1.08, 2.04, 2.14, 1.76, 1.17)
B<-c(1.69, 0.64, .9, 1.41, 1.01, .84, 1.28, 1.59) 
C<-c(1.56, 1.22, 1.32, 1.39, 1.33, 1.54, 1.04, 2.25, 1.49) 
D<-c(1.3, .75, 1.26, .69, .62, .9, 1.2, .32) 
E<-c(.73, .8, .9, 1.24, .82, .72, .57, 1.18, .54, 1.3)

## dis.coal<-makemultdata(A, B, C, D, E, 
##                        cuts = median(c(A, B, C, D, E)))
## temp<-multmixEM(dis.coal$y, lambda = dis.coal$lambda, 
##                 theta = dis.coal$theta)

## Now plot the components' CDF via the posterior probabilities

## compCDF(dis.coal$x, temp$posterior)
