epiBetaR {ecocbo}

Dataset containing an example of the results of applying ecocbo::sim_beta().

Description

The dataset contains the results of applying ecocbo::sim_beta() to epiDat. The result is a list with three levels. $Power A data frame with the results of statistical power according to different sampling efforts. $Results A data frame with the results of applying PERMANOVA to epiDat a number of times, it contains the values of pseudoF and the mean squares for different repeated sampling efforts. $alpha The value of Type I Error as chosen by the user.

This dataset can be used to study the variability of the pseudoF-statistic, beta and the power when an experiment is applied to a varying number of samples, sampling units, or sampling sites.

Usage

data("epiBetaR")

Format

An object of class "ecocbo_beta", also a list of two data frames and a numeric value. The format is:

$Power		a data frame that contains power levels at different experimental designs.
	m	number of sites.
	n	number of replicates within each site.
	Power	estimation of power for the experimental design.
	Beta	estimation of error type II for the experimental design.
	fCrit	value of observed F according to the required alpha.
$Results		a data frame that contains the results of the evaluation of sim_beta.
	dat.sim	simulation from which the results are obtained.
	k	number of resample for the result.
	m	number of sites considered for the result.
	n	number of replicates within each site for the result.
	pseudoFH0	observed F value for the experimental design, when all observations belong to one site.
	pseudoFHa	observed F value for the experimental design, when observations belong to different sites.
	AMSHa	calculated mean squares among sites in the experiment.
	RMSHa	calculated mean squares for the residuals in the experiment.
$alpha		a numeric value for the Type I Error as chosen by the user.

Details

This dataset comes from applying ecocbo::sim_beta() to the basic data from ecocbo::epiDat.
