lightspeed: Simon Newcomb's measurements of the speed of light

In evidence: Analysis of Scientific Evidence Using Bayesian and Likelihood Methods

Description

Simon Newcom's measured in the late 1900's the time it took light to cover a certain distance. The data are reported in Stigler(1977) and have been widely used since to illustrate statistical inference.

Usage

data(lightspeed)

Format

A vector with 66 observations of the travel time of light.

- Default priors may change, so it's safest to specify priors, even if equivalent to the defaults.
