kristof: Compute Kristof Coefficient

In Lambda4: Collection of Internal Consistency Reliability Coefficients.

Description

A reliability coefficient used for tests that are easily split into three parts.

Usage

  kristof(x, split.method = "triplet",
    missing = "complete", standardize = FALSE)

Arguments

x	Can be either a data matrix or a covariance matrix
split.method	Specify method for splitting items?
missing	How to handle missing values.
standardize	When TRUE Results are standardized by using the correlation matrix instead of the covariance matrix for computation.

Value

kristof	The Kristof estimate of reliability.
Split	The split used to obtain the reliability estimate.
