sampleData: Sampling Response of individuals within a SWD model

Description Usage Arguments Value Examples

Description

Sample data (response) for given numbers of individuals by given group means within a SWD model

Usage

1
2
sampleData(I, TP, mu, theta, beta.j, sigma.alpha, X.i.j.0, X.i.j = NULL, N,
  sigma.e, sigma.ind = NULL)

Arguments

I

number of clusters (design parameter)

TP

number of timepoints (design parameter)

mu

baseline mean (model parameter)

theta

treatment effect (model parameter)

beta.j

vector of time trents (model parameter)

sigma.alpha

between cluster variability as standard deviation (model parameter)

X.i.j.0

assumed treatment model matrix for a SWD study (model parameter)

X.i.j

data model matrix of real intervention implementation (model parameter), by default (NULL) the same as the X.i.j.0

N

number of individuals (fixed) for all clusters and timepoints

sigma.e

random error variability as standard deviation (model parameter)

sigma.ind

individual variability as standard deviation (model parameter), if it is an longitudinal model, by default (NULL) it is an cross-sectional model

Value

Data frame with individuals intensities corresponds to the SWD model and full model parameter information
