run_ICED: run ICED models

In ICED: IntraClass Effect Decomposition

run ICED models

Description

Wrapper function for lavaan to run an ICED model generated with ICED_syntax()

Usage

run_ICED(model = NULL, data = NULL, boot = NULL, ncores = NULL)

Arguments

model	lavaan model syntax, generated with ICED_syntax
data	specify data to be analysed - repeated measures variable names must correspond to separate variables in the data (wide format)
boot	run bootstrapped analysis to extract 95% CIs for the ICC and ICC2 estimates
ncores	specify the number of cores to run with boot, defaults to 1

Value

returns a list of estimated variances and reliability coefficients and the lavaan output

# generate data structure and syntax
struc <- data.frame(time = c("T1", "T2", "T3", "T4"),
day = c("day1","day1","day2","day2"),
session = c("ses1", "ses1","ses2", "ses3"))

syn <- iced_syntax(struc)

# generate data
sim1 <- sim_ICED(struc,
variances = list(time = 10,
               day = 2,
                 session = 1,
                 error = 3),
n = 2000)

res1 <- run_ICED(model = syn,
data = sim1$data)
