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

### Value

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