This function performs a jackknife estimation of NOHARM analysis to get standard errors based on a replication method (see Christoffersson, 1977).
R2noharm.jackknife(object, jackunits=NULL)# S3 method for R2noharm.jackknife
summary(object, logfile=NULL, ...)
A list of lists with following entries:
Data frame with parameters
List of estimated standard errors for all parameter estimates:
tanaka.stat, rmsr.stat, rmsea.stat,
chisquare_df.stat, thresholds.stat, final.constants.stat,
uniquenesses.stat, factor.cor.stat, loadings.stat,
loadings.theta.stat
List with obtained results by jackknifing for all parameters:
j.tanaka, j.rmsr, rmsea, chisquare_df,
j.pm, j.thresholds, j.factor.cor,
j.loadings, j.loadings.theta
Unique jackknife elements
Object of class R2noharm
A vector of integers or a number. If it is a number, then it refers to the number of jackknife units. If it is a vector of integers, then this vector defines the allocation of persons jackknife units. Integers corresponds to row indexes in the data set.
