Power Analysis for Interobserver Agreement Analysis.

Usage

kappaSizePower(
  outcome = "2",
  kappa0 = 0.4,
  kappa1 = 0.6,
  props = "0.20 , 0.80",
  raters = "2",
  alpha = 0.05,
  power = 0.8
)

Arguments

outcome

Number of outcome level.

kappa0

The null hypothesis value of kappa - the level of agreement the study tests against, versus the alternative kappa1. kappaSize documents this argument as "the null hypothesis for the kappa hypothesis test". It is NOT the anticipated value; kappaSizeCI and kappaSizeFixedN use kappa0 for the anticipated value, which is a different quantity.

kappa1

Expected value of kappa.

props

Proportions of outcome level.

raters

Number of raters.

alpha

Significance level.

power

Power.
