type_m {retrodesign}

type_m

Description

Calculates type m error. Is calculated using simulation, and thus supports t distributions through the df parameter.

Usage

type_m(A, s, alpha = 0.05, df = Inf, n.sims = 10000)

Arguments

A

a numeric or list, estimate(s) of the true effect size

s

a numeric, standard error of the estimate

alpha

a numeric, the statistical significance threshold

df

a numeric, the number of degrees of freedom. df=Inf is equivalent to a normal distribution.

n.sims

a numeric, how many times to simulate when calculating Type M error

Value

either the type m error, a numeric if a single A is provided, or a df of length 2 by A, with the effect size and corresponding type m error in each row.

Examples

type_m(1,3.28)
type_m(list(.2,2,20),8.1)
