Simulate data for Chapter 6.2: Two groups with equal variance

Description

Simulate wingspan measurements in female and male peregrines with equal variance.

Usage

simDat62(n1 = 60, n2 = 40, mu1 = 105, mu2 = 77.5, sigma = 2.75)

Arguments

n1	The sample size of females
n2	The sample size of males
mu1	The population mean males
mu2	The population mean females
sigma	The standard deviation for both groups

Value

A list of simulated data and parameters.

n1	Female sample size
n2	Male sample size
mu1	Female mean
mu2	Male mean
beta	Difference in wingspan mean between sexes
sigma	Standard deviation for both groups
x	Indicator variable for sex, 1 = male
y	Simulated wingspan data

Examples

str(dat <- simDat62())      # Implicit default arguments
str(dat <- simDat62(n1 = 1000, n2 = 10000)) # Much larger sample sizes

# Revert to "model-of-the-mean" (with larger sample size)
str(dat <- simDat62(n1 = 10000, n2 = 10000, mu1 = 105, mu2 = 105))
