combinevar: Combining Mean and Variances from Multiple Samples

Description

This function takes multiple mean and sample variance estimates and combines them.

Usage

combinevar(xbar = NULL, s_squared = NULL, n = NULL)

Arguments

xbar

vector of means

s_squared

vector of sample variances

n

vector of number of observations

Value

Vector containing the combined mean and sample variance.

Details

If a Monte Carlo simulation is run over 1000 loops and then again over another 1000 loops, one may wish to update
the mean and variance from the first 1000 loops with the second set of simulation results.
