Estimate the sample size needed to do an unpaired one-way test using betta

Description

Estimate the sample size needed to do an unpaired one-way test using betta

Usage

sample_size_estimate(
  control_group_est,
  se_est,
  diff = 5,
  alpha = 0.05,
  prop = 0.8,
  samples = 20,
  precision = 5
)

Arguments

control_group_est

An estimate of the alpha diversity parameter for the control group

se_est

An estimate of the (common) standard deviation

diff

An estimate of the difference between the control and non-control groups

alpha

Minimum significance level desired

prop

Desired power

samples

Number of bootstrap resamples used to estimate the sample size. Increase for a more accurate estimate.

precision

How much to increment the sample size as we try to increase the power

Value

An estimate of the necessary sample size and some details
