nobs.lcModel: Number of observations used for the lcModel fit

Description

Extracts the number of observations that contributed information towards fitting the cluster trajectories of the respective lcModel object. Therefore, only non-missing response observations count towards the number of observations.

Usage

# S3 method for lcModel
