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

In latrend: A Framework for Clustering Longitudinal Data

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 class 'lcModel'
nobs(object, ...)

Arguments

object	The lcModel object.
...	Additional arguments.
