Multimodel Inference
Sociological Methods and Research - Tập 33 Số 2 - Trang 261-304 - 2004
The model selection literature has been generally poor at reflecting the deep
foundations of the Akaike information criterion (AIC) and at making appropriate
comparisons to the Bayesian information criterion (BIC). There is a clear
philosophy, a sound criterion based in information theory, and a rigorous
statistical foundation for AIC. AIC can be justified as Bayesian using a “savvy”
prior on mode...
Normative Power and Conflict Potential
Sociological Methods and Research - Tập 4 Số 2 - Trang 237-263 - 1975
The return potential model for norms and roles is extended to yield concepts and
measures of normative power and conflict potential, conceived to be
complementary attributes of all normative systems. An input-output energy model
is proposed to represent the normative process, without assuming either
equilibrium tendencies or ego's motivation to conform. Organized, disorganized,
and unorganized sta...
Impact of a Confounding Variable on a Regression Coefficient
Sociological Methods and Research - Tập 29 Số 2 - Trang 147-194 - 2000
Regression coefficients cannot be interpreted as causal if the relationship can
be attributed to an alternate mechanism. One may control for the alternate cause
through an experiment (e.g., with random assignment to treatment and control) or
by measuring a corresponding confounding variable and including it in the model.
Unfortunately, there are some circumstances under which it is not possible to...
Testing for Lagged, Cotemporal, and Total Dependence in Cross-Lagged Panel Analysis
Sociological Methods and Research - Tập 16 Số 2 - Trang 187-217 - 1987
Panel studies are statistical studies in which two or more variables are
observed for two or more subjects at two or more points in time. Cross-lagged
panel studies are those studies in which the variables are continuous and divide
naturally into two sets. Focus is on estimating and testing the effects, or
impacts, of each set of variables on the other. In the regression approach the
cross-lagged ...
On Group Comparisons With Logistic Regression Models
Sociological Methods and Research - Tập 49 Số 2 - Trang 498-525 - 2020
It is widely believed that regression models for binary responses are
problematic if we want to compare estimated coefficients from models for
different groups or with different explanatory variables. This concern has two
forms. The first arises if the binary model is treated as an estimate of a model
for an unobserved continuous response and the second when models are compared
between groups that...
Snowball Sampling: Problems and Techniques of Chain Referral Sampling
Sociological Methods and Research - Tập 10 Số 2 - Trang 141-163 - 1981
In spite of the fact that chain referral sampling has been widely used in
qualitative sociological research, especially in the study of deviant behavior,
the problems and techniques involved in its use have not been adequately
explained. The procedures of chain referral sampling are not self-evident or
obvious. This article attempts to rectify this methodological neglect. The
article provides a de...
Selection Bias in Linear Regression, Logit and Probit Models
Sociological Methods and Research - Tập 18 Số 2-3 - Trang 360-390 - 1989
Missing data are common in observational studies due to self-selection of
subjects. Missing data can bias estimates of linear regression and related
models. The nature of selection bias and econometric methods for correcting it
are described. The econometric approach relies upon a specification of the
selection mechanism. We extend this approach to binary logit and probit models
and provide a simp...
A SAS Procedure Based on Mixture Models for Estimating Developmental Trajectories
Sociological Methods and Research - Tập 29 Số 3 - Trang 374-393 - 2001
This article introduces a new SAS procedure written by the authors that analyzes
longitudinal data (developmental trajectories) by fitting a mixture model. The
TRAJ procedure fits semiparametric (discrete) mixtures of censored normal,
Poisson, zero-inflated Poisson, and Bernoulli distributions to longitudinal
data. Applications to psychometric scale data, offense counts, and a dichotomous
prevalen...
Organizations and Survey Research
Sociological Methods and Research - Tập 47 Số 2 - Trang 240-276 - 2018
Surveys provide a critical source of data for scholars, yet declining response
rates are threatening the quality of data being collected. This threat is
particularly acute among organizational studies that use key informants—the mean
response rate for published studies is 34 percent. This article describes
several response enhancing strategies and explains how they were implemented in
a national s...
Alternative Ways of Assessing Model Fit
Sociological Methods and Research - Tập 21 Số 2 - Trang 230-258 - 1992
This article is concerned with measures of fit of a model. Two types of error
involved in fitting a model are considered. The first is error of approximation
which involves the fit of the model, with optimally chosen but unknown parameter
values, to the population covariance matrix. The second is overall error which
involves the fit of the model, with parameter values estimated from the sample,
to...
