This package provides facilities to date monazite using electron microprobe analysis (EPMA). More precisely, it has three main features:
from a set of analyses of the triplets (U,Th,Pb) contents and corresponding errors, it calculates the age of each analytical point by solving Equation (1) of Montel et al. (1996);
from these results, it estimates the common age(s) under the assumption that the analyses come from a given number of age populations and test for this assumption (chi2-test);
from the calculated ages, it estimates the most probable number of age populations from which the analyses come.

The package contains two main functions
calculate the ages and
tests, that test for the number of age
An example is provided with the data
