chisq.power {haplo.stats}R Documentation

Power and sample size for the chi-square distribution

Description

Power and sample size for the chi-square distribution given non-centrality, degrees of freedom, alpha, N (for chisq.power), and power (for chisq.sample.size)

Usage

chisq.power(n, nc, df, alpha)
chisq.power.dif(n, nc, df, alpha, power)
chisq.sample.size(nc, df=df, alpha, power, lower=20, upper=100000)

Arguments

n sample size (for power)
nc non-centrality parameter
df degrees of freedom
alpha type-I error rate
power desired power (for sample size)
lower lower bound for search space for sample size
upper upper bound for search space for sample size

Details

Value

power, the difference in power from target power, and sample size, respectively for the three different functions
