xclass(m1, m2)

Arguments

m1

an object inheriting from classes hlme, lcmm, multlcmm, Jointlcmm, mpjlcmm or externVar

m2

an object inheriting from classes hlme, lcmm, multlcmm, Jointlcmm, mpjlcmm or externVar

Value

the contingency table of the two classifications

Examples

## Estimation of the models
m2 <- hlme(Y~Time*X1,mixture=~Time,random=~Time,classmb=~X2+X3,subject='ID',ng=2,
data=data_hlme,B=c(0.11,-0.74,-0.07,20.71,29.39,-1,0.13,2.45,-0.29,4.5,0.36,0.79,0.97))
m3 <- hlme(fixed = Y ~ Time * X1, mixture = ~Time, random = ~Time,subject = "ID",
classmb = ~X2 + X3, ng = 3, data = data_hlme,B=c(-0.21, 0.31, -2.11, -0.81, -0.24,
-0.18, 25.4, 20.09, 30.18, -0.43, -1.1, 0.25, 2.37, -0.29, 2.34, 0.03, 0.74, 0.97))

## Compare the classifications
xclass(m2,m3)
# The 39 subjects in class 2 of m3 come from class 1 of m2.
# In the same way, all the subjects in class 3 come from class 2 of m2.
# Class 1 of m3 mixes subject from class 1 and class 2 of m2.
