In this article, we illustrate the command distrate, which calcu- lates age-standardized rates with efficient interval estimation by using formulas developed by Tiwari, Clegg, and Zou (2006, Statistical Methods in Medical Re- search 15: 547–569) as a modification of the method proposed by Fay...

We use microdata collected by the Italian National … estimated after controlling for observed confounding by using a propensity score weighting approach. To control for both … observed and unobserved confounding (better known as endogeneity), a semiparametric recursive bivariate probit approach is …

This paper presents a general method for nding optimal blocking arrangements of pure-level and mixed-level orthogonal designs of resolution 3. The method requires enumeration of all non-isomorphic `parent designs' that include the treatment factors as well as the future blocking factor. For all...

There is currently no general approach to orthogonally block two-level and multi-level orthogonal arrays and mixed-level orthogonal arrays. In this article, we present a mixed integer linear programming approach that seeks an optimal blocking arrangement for any type of regular and nonregular...

This paper deals both with the issues of confounding and of control, as the definition of a confounding factor is far … from universal and there exist different methodological approaches, ex ante and ex post, for controlling for a confounding …

The hypothesis is that Pareto and Kaldor-Hicks Efficiency have an aspect of sustainability in relation to inequality. The analysis finds efficient situations reached increasing inequality as diminishing in the long term effective demand in a larger measure than counterbalancing increases thanks...

Confounding is a major issue in observational epidemiological studies. This paper describes two postestimation commands … for assessing confounding effects. One command (confall) displays and plots all possible effect estimates against one of p …

An important problem in epidemiology and medical research is the estimation of a causal effect of a treatment action at a single point in time on the mean of an outcome within a population defined by strata of some of the observed covariates. Marginal structural models (MSM) are models for...
