BiasVarTO {evidence}

a simple example of the bias–variance trade-off.

Description

A total of eight models are fitted to a data set consisting of seven predictors. The response is the exact fit with a variable amount of zero-mean noise added. This is repeated a certain number of times (by default, 100 times). Plots of Bias^2 and variance vs. the number of parameters are produced.

Usage

BiasVarTO(times = 100)

Arguments

times

the number of repeats to average bias and variance over (default 100)

Value

none produced, the function produces two plots
