In rpsychologist/powerlmm: Power Analysis for Longitudinal Multilevel Models

Calculate the subject-level ICC at pretest

Description

Calculate the subject-level ICC at pretest

Usage

get_ICC_pre_subjects(object, ...)

Arguments

object	An object created by study_parameters
...	Optional named arguments.

Value

Returns the proportion of baseline variance at the subject level (which also includes cluster-level variance), as a numeric vector.

Examples

paras <- study_parameters(n1 = 11,
                          n2 = 10,
                          n3 = 3,
                          T_end = 10,
                          sigma_subject_intercept = 1.2,
                          sigma_subject_slope = 0.2,
                          sigma_cluster_intercept = 0.5,
                          sigma_cluster_slope = 0.2,
                          sigma_error = 1.2,
                          cohend = -0.8)
