A STATISTICAL ANALYSIS OF DIFFERENCE TESTS WITH REPLICATIONS

Journal of Sensory Studies, 1994
ABSTRACTThis paper proposes a statistical method for difference tests with repetitions. Classical methods for difference tests are based upon the binomial distribution, and are not concerned with the number of repetitions per judge. But when more than one replication of a difference test is required, judgements from different judges are more ...

Statistical Comparison of Original and Replicated Surfaces

2019
This article is focused on the statistical comparison of the original and replicated surface. Surface replication has been used for a long time, but recently a material with the commercial name Dentacryl™ has been used for the replication. However, this material has some disadvantages that outweigh the benefits.

Science with or without statistics: Discover-generalize-replicate? Discover-replicate-generalize?

Behavioral and Brain Sciences, 2022
AbstractOverstated generalizability (external validity) is common in research. It may coexist with inflation of the magnitude and statistical support for effects and dismissal of internal validity problems. Generalizability may be secured before attempting replication of proposed discoveries or replication may precede efforts to generalize.

Prediction of Success in Elementary Statistics: Three Replications [PDF]

Psychological Reports, 1976
Validity of 3 prognosis tests to predict success in elementary statistics was determined for 3 separate classes. The criterion was a composite test of 100 concepts, problems, and open-ended exercises. In all 3 classes, competence in algebra and in the ability to grasp and use meanings of newly defined symbols gave the optimum regression equations ...

Mutation–Replication Statistics of Polymerase Chain Reactions

Journal of Computational Biology, 2002
The variability of the products of polymerase chain reactions, due to mutations and to incomplete replications, can have important clinical consequences. Sun (1995) and Weiss and von Haeseler (1995) modeled these errors by a branching process and introduced estimators of the mutation rate and of the efficiency of the reaction based, for example, on the

The statistical power of replications in difference tests

Food Quality and Preference, 2003
Abstract The binomial test with N = nk observations is frequently used when n assessors each perform k replicated difference tests, for instance triangle tests. The power of this test, until now completely unknown for k >1, is studied. Beta-binomial, generalized linear mixed and binomial mixture models are compared and shown to give similar ...

Critical Replications for Statistical Design

1988
While writing a new book [Wiley ’87] I found several distinct statistical problems, each with a separate solution, but all in need of a higher principle of justification. I looked in vain into statistics for a higher principle or criterion which we need to serve as a common foundation for those similar solutions.

Statistics and replication experiments: Comparing interaction effects

Cognitive Therapy and Research, 1989
A method is presented that allows the comparison and combination of interaction effects obtained in two or more experiments. Using an analysis of variance model, we first evaluated the interaction effects found in experiments conducted by Alloy and Abramson (1979, Experiment 2) and Bryson, Doan, and Pasquali (1984).

Statistical Significance and the Replication Crisis in the Social Sciences

2019
The recent “replication crisis” in the social sciences has led to increased attention on what statistically significant results entail. There are many reasons for why false positive results may be published in the scientific literature, such as low statistical power and “researcher degrees of freedom” in the analysis (where researchers when testing a ...

Statistical analysis of controlled calibration model with replicates

Journal of Statistical Computation and Simulation, 2013
In this work, we generalize the controlled calibration model by assuming replication on both variables. Likelihood-based methodology is used to estimate the model parameters and the Fisher information matrix is used to construct confidence intervals for the unknown value of the regressor variable. Further, we study the local influence diagnostic method
