Regression Analysis of Proportion Outcomes with Random Effects

  title={Regression Analysis of Proportion Outcomes with Random Effects},
  author={Colman Humphrey and Daniel Swingley},
  journal={arXiv: Methodology},
A regression method for proportional, or fractional, data with mixed effects is outlined, designed for analysis of datasets in which the outcomes have substantial weight at the bounds. In such cases a normal approximation is particularly unsuitable as it can result in incorrect inference. To resolve this problem, we employ a logistic regression model and then apply a bootstrap method to correct conservative confidence intervals. This paper outlines the theory of the method, and demonstrates its…

Bilingualism Affects Infant Cognition: Insights From New and Open Data

Abstract Bilingualism has been hypothesized to shape cognitive abilities across the lifespan. Here, we examined the replicability of a seminal study that showed monolingual–bilingual differences in

A cross-linguistic examination of toddlers' interpretation of vowel duration.

The results suggest a strong capacity for phonetic analysis in children before their second birthday, and find that word recognition in Dutch toddlers was affected by shortening but not lengthening of vowels, matching an asymmetry also found in Dutch adults.

Econometric Methods for Fractional Response Variables with an Application to 401(K) Plan Participation Rates

We offer simple quasi-likelihood methods for estimating regression models with a fractional dependent variable and for performing asymptotically valid inference. Compared with log-odds type

Bootstrapping data arrays of arbitrary order

In this paper we study a bootstrap strategy for estimating the variance of a mean taken over large multifactor crossed random effects data sets. We apply bootstrap reweighting independently to the

Uncertainty in online experiments with dependent data: an evaluation of bootstrap methods

This work develops a framework for understanding how dependence affects uncertainty in user-item experiments and evaluates how bootstrap methods that account for differing levels of dependence perform in practice, and highlights the importance of analysis of inferential methods for complex dependence structures common to online experiments.


Recently there has been much interest in data that, in statistical language, may be described as having a large crossed and severely unbalanced random effects structure. Such data sets arise for

A Heteroskedasticity-Consistent Covariance Matrix Estimator and a Direct Test for Heteroskedasticity

This paper presents a parameter covariance matrix estimator which is consistent even when the disturbances of a linear regression model are heteroskedastic. This estimator does not depend on a formal

Using Effect Size-or Why the P Value Is Not Enough.

Effect size helps readers understand the magnitude of differences found, whereas statistical significance examines whether the findings are likely to be due to chance. Both are essential for readers

An Introduction to the Bootstrap

Statistics is the science of learning from experience, especially experience that arrives a little bit at a time. The earliest information science was statistics, originating in about 1650. This
