Artiodactyla

The Artiodactyla analysis supports Type II survivorship because the semi-log transformation gives the strongest fit. The Artiodactyla example is limited because the abstract lacks sample sizes, confidence intervals, regression coefficients, p-values, occurrence counts, binning rules, and detailed filtering procedures. The worked example uses fossil-record survivorship for Artiodactyla genera from the NOW database. Artiodactyla include even-toed ungulates such as antelopes, pigs, hippos, and related groups.
