Infectious Surgical Complications are Not Dichotomous

Annals of Surgery, 2018
To characterize reasons for discordance between administrative data and registry data in the determination of postoperative infectious complications.Data regarding the occurrence of postoperative surgical complications are identified through either administrative or registry data.

Higher‐order factor analysis of an instrument with dichotomous data

Research in Nursing & Health, 2005
AbstractThis article reports the use of higher‐order factor analysis to examine the underlying dimensions of an instrument designed to measure community acceptance of nurse practitioners/physician's assistants. The instrument consisted of both dichotomous and Likert scale items. Use of factor analysis with dichotomous data is controversial.

The Need for Mixed-Effects Modeling with Population Dichotomous Data

Journal of Pharmacokinetics and Pharmacodynamics, 2001
Over the past 25 years sophisticated data analytic techniques have been developed which can lead to improved analyses, but at additional computational cost. In particular, this applies to the approach where interindividual random effects are included in a data analytic model for population pharmacokinetic data, which can often lead to substantially ...

A Latent Trait Model for Dichotomous Choice Data

Psychometrika, 1990
The PARELLA model is a probabilistic parallelogram model that can be used for the measurement of latent attitudes or latent preferences. The data analyzed are the dichotomous responses of persons to stimuli, with a one (zero) indicating agreement (disagreement) with the content of the stimulus.

Two-Level Nonparametric Scaling for Dichotomous Data

2001
This chapter considers a two-level design where the objects to be scaled are the higher-level units. Nested within each object are lowerlevel units, called subjects, and a set of dichotomous items is administered to each subject. The subjects are regarded as strictly parallel tests for the objects.

An Irt-Based Model for Dichotomous Longitudinal Data

Psychometrika, 1989
The LLRA (linear logistic model with relaxed assumptions; Fischer, 1974, 1977a, 1977b, 1983a) was developed, within the framework of generalized Rasch models, for assessing change in dichotomous item score matrices between two points in time; it allows to quantify change on latent trait dimensions and to explain change in terms of treatment effects ...

Robust Contingent Values Based on Dichotomous Choice Survey Data

Environmetrics, 1997
Estimated willingness-to-pay (WTP) is considered in the context of dichotomous choice referendum surveys. The sensitivity or robustness of estimates is investigated when some members of the population do not respond consistent with how they would vote in a real referendum. The majority of responses are presumed to be consistent with reservation prices.

An objective Bayesian analysis of dichotomous sensitive data

2012
We consider a dichotomous population in which every person belongs either to a sensitive group $A$ or to the non sensitive complement $\bar{A}$. The object of interest is to estimate the population proportion of individuals who are members of $A$. We refer to a randomized response model proposed by Huang (2004), where also another parameter is present,

Notes on Testing Equality in Dichotomous Data with Matched Pairs

Biometrical Journal, 2001
Summary: In attempting to improve the efficiency of McNemar's test statistic [\textit{Q. McNemar}, Psychometrika 12, 153-157 (1947)] we develop two test procedures that account for the information on both the discordant and concordant pairs for testing equality between two comparison groups in dichotomous data with matched pairs. Furthermore, we derive
