Likelihood Methods for Testing Group Problem Solving Models with Censored Data.
Peer reviewed Peer reviewed
Regal, Ronald R.; Larntz, Kinley – Psychometrika, 1978
Models relating individual and group problem solving solution times under the condition of limited time (time limit censoring) are presented. Maximum likelihood estimation of parameters and a goodness of fit test are presented. (Author/JKS)

Estimating Trends from Censored Assessment Data under No Child Left Behind
Peer reviewed Peer reviewed

Furgol, Katherine E.; Ho, Andrew D.; Zimmerman, Dale L. – Educational and Psychological Measurement, 2010
Under the No Child Left Behind Act, large-scale test score trend analyses are widespread. These analyses often gloss over interesting changes in test score distributions and involve unrealistic assumptions. Further complications arise from analyses of unanchored, censored assessment data, or proportions of students lying within performance levels…

Tuma, Nancy Brandon; Hannan, Michael T. – 1977
The document, part of a series of chapters described in SO 011 759, considers the problem of censoring in the analysis of event-histories (data on dated events, including dates of change from one qualitative state to another). Censoring refers to the lack of information on events that occur before or after the period for which data are available.…

Final Report for Dynamic Models for Causal Analysis of Panel Data. Quality of Maximum Likelihood Estimates of Parameters in a Log-Linear Rate Model. Part III, Chapter 3.
Fennell, Mary L.; And Others – 1977
This document is part of a series of chapters described in SO 011 759. This chapter reports the results of Monte Carlo simulations designed to analyze problems of using maximum likelihood estimation (MLE: see SO 011 767) in research models which combine longitudinal and dynamic behavior data in studies of change. Four complications--censoring of…

Estimation of Effect Size Under Nonrandom Sampling: The Effects of Censoring Studies Yielding Statistically Insignificant Mean Differences.
Peer reviewed Peer reviewed
Hedges, Larry V. – Journal of Educational Statistics, 1984
If the quantitative result of a study is observed only when the mean difference is statistically significant, the observed mean difference, variance, and effect size are biased estimators of corresponding population parameters. The exact distribution of sample effect size and the maximum likelihood estimator of effect size are derived. (Author/BW)

Final Report for Dynamic Models for Causal Analysis of Panel Data. Alternative Estimation Procedures for Event-History Analysis: A Monte Carlo Study. Part III, Chapter 5.
Carroll, Glenn R.; And Others – 1978
This document is part of a series of chapters described in SO 011 759. The chapter examines the merits of four estimators in the causal analysis of event-histories (data giving the number, timing, and sequence of changes in a categorical dependent variable). The four procedures are ordinary least squares, Kaplan-Meier least squares, maximum…

Final Report for Dynamic Models for Causal Analysis of Panel Data. The Impact of Measurement Error in the Analysis of Log-Linear Rate Models: Monte Carlo Findings. Part III, Chapter 4.
Carroll, Glenn R.; And Others – 1978
This document is part of a series of chapters described in SO 011 759. The chapter advocates the analysis of event-histories (data giving the number, timing, and sequence of changes in a categorical dependent variable) with maximum likelihood estimators (MLE) applied to log-linear rate models. Results from a Monte Carlo investigation of the impact…
