Statistical and Substantive 1 Running head: STATISTICAL AND SUBSTANTIVE CHECKING Statistical and Substantive Checking in Growth Mixture Modeling
نویسنده
چکیده
This commentary discusses the Bauer and Curran (2002) investigation of growth mixture modeling. Single-class modeling of non-normal outcomes is compared to modeling with multiple latent trajectory classes. New statistical tests of multiple-class models are discussed. Principles for substantive investigation of growth mixture model results are presented and illustrated by an example of high school dropout predicted by low mathematics achievement development in grades 7 10.

Error statistical modeling and inference: Where methodology meets ontology
In empiricalmodeling, an important desiderata for deeming theoretical entities and processes as real is that they can be reproducible in a statistical sense. Current day crises regarding replicability in science intertwines with the question of how statistical methods link data to statistical and substantive theories and models. Different answers to this question have important methodological c...
متن کاملInterpreting the substantive significance of multivariable regression coefficients
A critical objective for applications of multivariable regression analysis is evaluation of both substantive importance and statistical significance, yet many articles focus excessively on inferential statistical tests at the expense of substantive issues. I demonstrate approaches for writing clear sentences to interpret the real-world meaning of estimated coefficients from ordinary least squar...
متن کاملStatistical Model Specification and Validation: Statistical vs. Substantive Information
Statistical model specification and validation raise crucial foundational problems whose pertinent resolution holds the key to learning from data by securing the reliability of frequentist inference. The paper questions the judiciousness of several current practices, including the theory-driven approach, and the Akaike-type model selection procedures, arguing that they often lead to unreliable ...
متن کاملModel Validation and DSGE Modeling
The primary objective of this paper is to revisit DSGE models with a view to appraise their statistical adequacy and propose ways to ameliorate their empirical pertinence. This paper brings out several weaknesses of the traditional DSGE modeling, including statistical misspecification, non-identification of deep parameters, substantive inadequacy, weak forecasting performance and potentially mi...
متن کاملWhere do statistical models come from? Revisiting the problem of specification
R. A. Fisher founded modern statistical inference in 1922 and identified its fundamental problems to be: specification, estimation and distribution. Since then the problem of statistical model specification has received scant attention in the statistics literature. The paper traces the history of statistical model specification, focusing primarily on pioneers like Fisher, Neyman, and more recen...
