On regression adjustments to experimental data
Regression adjustments are often made to experimental data. Since randomization does not justify the models, almost anything can happen. Here, we evaluate results using Neyman’s non-parametric model, where each subject has two potential responses, one if treated and the other if untreated. Only one of the two responses is observed. Regression estimates are generally biased, but the bias is smal...
متن کامل“ Agnostic Notes on Regression Adjustments to Experimental Data : Reexamining
• Section 2 defines the basic notation; • Section 4.2.1 states Conditions 1–3; • Section 4.2.2 defines the vectors Qa and Qb and the prediction errors ai and bi , and introduces the σx and σx,y notation for population variances and covariances; • Section 5 defines the vector Q and the prediction errors a∗∗ i and b∗∗ i . Let p̃A = nA/n [as in remark (iii) after Corollary 1.2]. Extend Section 2’s ...
متن کاملAgnostic Notes on Regression Adjustments to Experimental Data: Reexamining Freedman’s Critique By
Freedman [Adv. in Appl. Math. 40 (2008) 180–193; Ann. Appl. Stat. 2 (2008) 176–196] critiqued ordinary least squares regression adjustment of estimated treatment effects in randomized experiments, using Neyman’s model for randomization inference. Contrary to conventional wisdom, he argued that adjustment can lead to worsened asymptotic precision, invalid measures of precision, and small-sample ...
متن کاملExtension of Logic regression to Longitudinal data: Transition Logic Regression
Logic regression is a generalized regression and classification method that is able to make Boolean combinations as new predictive variables from the original binary variables. Logic regression was introduced for case control or cohort study with independent observations. Although in various studies, correlated observations occur due to different reasons, logic regression have not been studi...
متن کاملA Review on the Hydrodynamic Characteristics of the SPP Concerning to the Available Experimental Data and Evaluating Regression Polynomial Functions
Surface-piercing propellers have been widely used in light and high-speed vessels because of their superior performance. One of the major steps in propeller selection algorithm is the determination of thrust as well as torque hydrodynamic coefficients. For the purpose of simplifying design and selection procedure, some relations are presented for determining hydrodynamic coefficients in some st...
