    According to Jacqueline Friedland's "Estimating Unpaid Claims Using Basic Techniques," there are seven steps to apply the chain-ladder technique: Compile claims data in a development triangle; Calculate age-to-age factors; Calculate averages of the age-to-age factors; Select claim development factors; Select tail factor

  3. Ternary plot - Wikipedia

    en.wikipedia.org/wiki/Ternary_plot

    A ternary flammability diagram, showing which mixtures of methane, oxygen gas, and inert nitrogen gas will burn. A ternary plot, ternary graph, triangle plot, simplex plot, or Gibbs triangle is a barycentric plot on three variables which sum to a constant. [1] It graphically depicts the ratios of the three variables as positions in an ...

    Triangular diagrams are not commonplace. The easiest way to understand them is to briefly go through three basic steps in their construction. Consider the first triangular diagram below, which shows all possible mixtures of methane, oxygen and nitrogen. Air is a mixture of about 21 volume percent oxygen, and 79 volume percent inerts (nitrogen ...
