Corrigendum to

“Marginal Effects in

Interaction Models:

Determining and

Controlling the False

Positive Rate”

Justin Esarey1 and Jane L. Sumner2

Abstract

After publication of Esarey and Sumner, we recognized substantively

significant errors in the paper. We correct those errors here. We discovered

these errors as part of work on another, unrelated paper to which one

co-author hoped to apply similar methods. The Brambor etal. procedure

is overconfident when separately testing multiple hypotheses, as correctly

stated in our paper. However, when conjointly testing multiple hypotheses,

the Brambor et al. procedure is appropriate. The procedure we suggest

on pp. 1161–1163 to correct for overconfidence in the case of separate

testing of multiple hypothesis (based on Benjamini and Hochberg) is (to our

knowledge) correct, but subject to several limitations unstated in the paper.

This corrigendum lays out all errors and limitations and adds a more robust

procedure to our interactionTest software.
