Statistical models with dichotomous response
Statistical models with dichotomous response are investigated. Many techniques for modeling such situations are discussed which involve various types of distributions. The two distributions which shall be discussed further are those related to probit and logit analysis. Several estimation methods …

Development of a semivolatile aerosol dichotomous sampler
… used to develop the semivolatile aerosol dichotomous sampler (SADS) and their results. The first section describes the theoretical background of SADS and the validation of its performance using numerical simulations and experimental data. SADS was proposed as an alternative method to …

Is conscious perception a continuous or dichotomous phenomenon?
… by the global neuronal workspace theory, the dichotomous view (e.g. Sergent and Dehaene, 2004) proposes that visual experience is all-or-none, and that someone is always either fully conscious or fully unconscious of visual phenomena. Opposed to this is a graded view (e.g. Overgaard, Rote, …

Least squares estimation for latent variables with dichotomous item response data
A new method for estimating the ability parameters in the statistical models based on item response theory (IRT) was presented in this study. A brief review of existing parameter estimation methods suggested the utility of a parameter estimation method which requires no specific assumption. By …

Computationally Efficient Multiuser and MIMO Detection based on Dichotomous Coordinate Descent Iterations
… performance. These detectors are based on Dichotomous Coordinate Descent (DCD) iterations, which are multiplication and division free, and therefore are attractive for real-time implementation. We propose a box-constrained DCD algorithm, and apply it to multiuser detection. We also design …

Dichotomous and polytomous item response model estimation using the marginal maximum likelihood and the EM algorithm
… the independent, latent predictor variables. For dichotomously scored items, the probability of a correct response can be described by one of the various dichotomous Item Response Models, namely the Rasch Model (Rasch, 1961), the Two-Parameter Logistic Model (Birnbaum, 1968) and the …

Latent trait, factor, and number endorsed scoring of polychotomous and dichotomous responses to the Common Metric Questionnaire
… three approaches to scoring polychotomous and dichotomous responses from the frequency and importance scales of the Common Metric Questionnaire (CMQ). Factor, latent trait, and number endorsed scores were estimated from the responses of 2684 job incumbents in six organizations. Scores from four …

Modification of a dichotomous tactile stimulation technique for left and right hemispheric specialization in normal and dyslexic readers
… in normal and dyslexic male readers using a dichotomous tactile stimulation technique. The study was a modification of Witelson's (1974; 1976) studies using non-verbal (shapes) and verbal (letters) stimuli. An additional verbal (objects) task, in which subjects recognized and verbally …

Models and Their Artists: The Dichotomous Representation of Women in The Unknown Masterpiece, Manette Salomon and The Masterpiece
This thesis proposes to analyze the dichotomous representation of the female model as benevolent and malevolent in three 19th-century French novels. Honoré de Balzac's The Unknown Masterpiece (1834), Jules and Edmond de Goncourt's Manette Salomon (1867), and Émile Zola's The Masterpiece (1886) are …

Beurling-Lax Representations of Shift-Invariant Spaces, Zero-Pole Data Interpolation, and Dichotomous Transfer Function Realizations: Half-Plane/Continuous-Time Versions
Given a full-range simply-invariant shift-invariant subspace <i>M</i> of the vector-valued <i>L<sup>2</sup></i> space on the unit circle, the classical Beurling-Lax-Halmos (BLH) theorem obtains a unitary operator-valued function <i>W</i> so that <i>M</i> may be represented as the image of of the …

A study of biting midge populations and an assessment of Bluetongue virus presence in southern Ontario, with a visual dichotomous key to the North American genera of Ceratopogonidae
… of their dispersal patterns. Finally, a dichotomous key to the Nearctic biting midge genera was constructed and illustrated with high-definition photography to show key characters. This key aids with taxonomic identification of the 35 recognized genera occurring north of Mexico.

Effects of respondent training on self-report personality assessment: an item response theory approach
… of response categories (i.e. polytomous vs. dichotomous) on item performance, model-data fit, and criterion-related validity. Participants recruited from MTurk (n = 1977) were randomly assigned to 1 of the 4 groups differing in training (i.e. training vs. no training) and response scale (i.e. …

Disclosure in Annual Reports: An Agency Theoretic Perspective in an International Setting
… indices, i.e. the disclosure point average for dichotomous, modified dichotomous weighted dichotomous and weighted modified dichotomous indices. These weighted indices were established by analysing survey responses of investment analysts. The results show that there were significant differences …

When Comparison Becomes Contrast: Choice in an Oppositional Framework
… proximal factors could, in some sense, prime dichotomous thinking. Dichotomous or oppositional thinking, as it is defined in this dissertation, pertains to the flattening of dimensions present in a choice set such that the items can be graphically depicted at two ends of one dimension (see …

Application of a Graded Response Model to the Assessment of Job Satisfaction
… made of the person and item parameters with the dichotomously scored counterparts. Application of the graded response model was also made to appropriateness measurement in detecting aberrant response vectors. The results demonstrated that graded response scoring can be a valid alternative to …

Assessing The Dimensionality of Polytomous Item Exams
… of statewide standardized tests contain both dichotomous and polytomous items, much of the work in dimensionality assessment has focused on the case of dichotomous item exams. The proposed method in this dissertation, Poly-NEWDIM (PND), demonstrates closer to nominal Type I error control and …
