Acidity | R Documentation |
Acidity index measured in a sample of 155 lakes in North-Central Wisconsin.
Crawford et al. (1992) and Crawford (1994) analyzed these data as a mixture of normal distributions on the log-scale. Richardson and Green (1997) used a normal mixture estimated using reversible jump MCMC.
