In dsouthwell/TestPackagev2: Spatially explicit power analysis in dynamic landscapes

Description

This function returns a critical value needed to calculate confidence intervals around the trend parameter given the Type I error rate and whether it is a one or two-tailed significance test.

Usage

sig.test(two.tailed, alpha)

Arguments

two.tailed	Set to TRUE for a two-tailed test, FALSE for a one-tailed test.
alpha	Set the type one error rate. Choose between 0.1, 0.05 and 0.01

Examples

#Return the critical value for a two-tailed test with a significance level of 0.05
two.tailed <- TRUE
alpha <- 0.05
sig.test(two.tailed, alpha)

#Return the critical value for a one-tailed test with a significance level of 0.1
two.tailed <- FALSE
alpha <- 0.1
