Control Variables in Interactive Models

چکیده
ABSTRACT Accounting studies often examine whether the relation between X and Y varies with a moderating variable, M, by including an interactive term, × in regression. We provide plain-English guidance on why, how, when to use control variables, Z, interaction tests. A simulation simple descriptions demonstrate how interacted controls affect coefficient estimates interpretations. In particular, we controlling for Z without accompanying of and/or M generally does not eliminate confounding effect M. conclude future research.

Bootstrapping Errors-in-Variables Models
The bootstrap is a numerical technique, with solid theoretical foundations, to obtain statistical measures about the quality of an estimate by using only the available data. Performance assessment through bootstrap provides the same or better accuracy than the traditional error propagation approach, most often without requiring complex analytical derivations. In many computer vision tasks a reg...
متن کاملCVcat: an interactive database on cataclysmic variables
CVcat is a database that contains published data on cataclysmic variables and related objects. Unlike in the existing online sources, the users are allowed to add data to the catalogue. The concept of an “open catalogue” approach is reviewed together with the experience from one year of public usage of CVcat. New concepts to be included in the upcoming AstroCat framework and the next CVcat impl...
متن کاملBad Variables Under Control
We give a fully abstract game model for Idealized Algol with non-local control flow. In contrast to most previous papers on game semantics, we do not need to include the bad-variable constructor mkvar to obtain full abstraction. Using the model we show that, unlike in the “control-free” case, the presence of mkvar does affect observational equivalence. We conclude by discussing the effect of mk...
