NregFix {flexmix} | R Documentation |
A simple artificial regression example with 3 latent classes, two independent variables, one concomitant variable and a dependent variable which follows a Gaussian distribution.
data("NregFix")
A data frame with 200 observations on the following 5 variables.
x1
Independent variable: numeric variable.
x2
Independent variable: a factor with two levels:
0
and 1
.
w
Concomitant variable: a factor with two levels:
0
and 1
.
y
Dependent variable.
class
Latent class memberships.
