neumann: Neumann dataset

Description Usage Format References Examples

Description

Willard Gibbs discovered a theoretical formula connecting the density, the pressure, and the absolute temperature of a mixture of gases with convertible components. He applied this formula and the estimated constants to 65 experiments of Neumann, and he discusses the systematic and accidental divergences (residuals).
