nobs2: Effective Sample Size.

In bozenne/lavaSearch2: Tools for Model Specification in the Latent Variable Framework

Effective Sample Size.

Description

Extract the effective sample size, i.e. sample size minus the loss in degrees of freedom caused by the estimation of the parameters.

Usage

nobs2(object, ssc, ...)

## S3 method for class 'lvmfit'
nobs2(object, ssc = lava.options()$ssc, ...)

## S3 method for class 'lvmfit2'
nobs2(object, ...)

Arguments

object	a lvmfit or lvmfit2 object (i.e. output of lava::estimate or lavaSearch2::estimate2).
ssc	[character] method used to correct the small sample bias of the variance coefficients: no correction ("none"/FALSE/NA), correct the first order bias in the residual variance ("residual"), or correct the first order bias in the estimated coefficients "cox"). Only relevant when using a lvmfit object.
...	additional argument passed to estimate2 when using a lvmfit object.

Details

When argument object is a lvmfit object, the method first calls estimate2 and then extract the leverage.

Value

Numeric vector of length the number of endogenous variables.
