R2noharm.jackknife.Rd
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, ...)
object | Object of class |
---|---|
jackunits | 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. |
logfile | File name if the summary should be sunk into a file |
... | Further arguments to be passed |
