Stochastic Variation: A Comment on Lewis-Beck and Skalaban's "The R-Squared"

In an interesting and provocative article, Michael Lewis-Beck and Andrew Skalaban make an important contribution by emphasizing several philosophical issues in political methodology that have received too little attention from methodologists and quantitative researchers. These issues involve the role of systematic, and especially stochastic, variation in statistical models. After briefly discus...

We discuss and give elementary proofs of results of Brion and of LawrenceVarchenko on the lattice-point enumerator generating functions for polytopes and cones. While this note is purely expository, its contains a new proof of Brion’s Theorem using irrational decompositions.

The Intrinsic Estimator, Alternative Estimates, and Predictions of Mortality Trends: A Comment on Masters, Hummer, Powers, Beck, Lin, and Finch

In this article, we discuss a study by Masters et al. (2014), published in Demography. Masters and associates estimated age, period, and cohort (APC) effects on U.S. mortality rates between 1959 and 2009 using the intrinsic estimator (IE). We first argue that before applying the IE, a grounded theoretical justification is needed for its fundamental constraint on minimum variance of the estimate...
