get_M: Calculate the total number of clusters.

In jm3594/crtpower: Power Analysis Functions for Cluster Randomized Trials

Description

Calculate the total number of clusters.

Usage

get_M(alpha = 0.05, power = 0.8, ICC = 0.001, delta = 0.2, n = 100,
  type = "standard", cv = NULL, tol = .Machine$double.eps^0.25)

Arguments

alpha	The level of significance.
power	The power.
ICC	The intra class correlation.
delta	The effect size.
n	The mean cluster size.
type	The type of design effect, either standard or based on the coefficient of variation.
cv	The coefficient of variation, if type is cv.
tol	A tolerance value.

Value

M The total number of clusters.
