calc_t: Evaluates power functions for power.t.test

In CTU-Basel/shinysse: Sample size estimation demo shiny app

Description

For all pre-set combinations of n, theta, xi and alpha, this function calculates a list of powCalc objects and saves the list.

Usage

calc_t(n, theta, xi, alpha, type, save_path)

Arguments

n	numeric vector containing possible range of sample sizes
theta	numeric vector containing possible range of effect sizes
xi	numeric vector containing possible range of standard deviations
alpha	numeric vector containing possible range of significance levels
type	string of value "two.sample", "one.sample", or "paired"
save_path	string inidicating where the function output should be saved

Details

Input parameters are optional. Defaults:

• n <- seq(from = 5, to = 2000, by = 5)

• theta <- seq(from = 1, to = 50, by = 1)

• xi <- seq(from = 1, to = 80, by = 1)

• alpha <- c(0.01, 0.025, 0.05)

• save_path <- file.path("inst", "extdata", "calc_t_test.rds")

Value

list of calculated powCalc objects
