A validity index based on cluster symmetry [PDF]

open access: yes2007 IEEE International Conference on Systems, Man and Cybernetics, 2007
An important consideration in clustering is the determination of the correct number of clusters and the appropriate partitioning of a given data set. In this paper, a newly developed point symmetry distance is used to propose a new cluster validity index named Sym -index which provides a measure of "symmetricity" of the different partitionings of a ...

Predicting Chronicity in Children and Adolescents With Newly Diagnosed Immune Thrombocytopenia at the Timepoint of Diagnosis Using Machine Learning‐Based Approaches

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Objectives To identify predictors of chronic ITP (cITP) and to develop a model based on several machine learning (ML) methods to estimate the individual risk of chronicity at the timepoint of diagnosis. Methods We analyzed a longitudinal cohort of 944 children enrolled in the Intercontinental Cooperative immune thrombocytopenia (ITP) Study ...

A novel profit-based validity index approach for feature selection in credit risk prediction

open access: yesAIMS Mathematics
Establishing a reasonable and effective feature system is the basis of credit risk early warning. Whether the system design is appropriate directly determines the accuracy of the credit risk evaluation results. In this paper, we proposed a feature system

Generative Roles: Assessing Sustained Involvement in Generativity [PDF]

open access: yes, 2015
Generative roles refer to observable, behavioral community positions that embody aspects of teaching and nurturing that are central to the concept of generativity. Two studies are presented that describe generative roles in a community sample and provide

Electricity load profile classification using Fuzzy C-Means method [PDF]

open access: yes, 2008
This paper presents the Fuzzy C-Means (FCM) clustering method. The FCM technique assigns a degree of membership for each data set to several clusters, thus offering the opportunity to deal with load profiles that could belong to more than one group at ...

A validity index for the MMPI-2 [PDF]

open access: yesArchives of Clinical Neuropsychology, 2002
There have been numerous methods developed for the detection of valid profiles on the Minnesota Multiphasic Personality Inventory (MMPI)-2. The current study examined a method of combining seven different validity scales of the MMPI-2 into a common weighted method in assessing malingering in chronic pain patients.

A longitudinal validation of the EQ-5D-5L and EQ-VAS stand-alone component utilising the Oxford Hip Score in the Australian hip arthroplasty population

open access: yesJournal of Patient-Reported Outcomes, 2022
Purpose To evaluate the measurement properties of the Oxford Hip Score (OHS), EQ-5D-5L utility index and EQ-5D-5L visual analogue scale (EQ-VAS) in patients undergoing elective total hip arthroplasty in Australia. Methods In this prospective multi-centre

q-thermostatistics and the analytical treatment of the ideal Fermi gas [PDF]

open access: yes, 2003
We discuss relevant aspects of the exact q-thermostatistical treatment for an ideal Fermi system. The grand canonical exact generalized partition function is given for arbitrary values of the nonextensivity index q, and the ensuing statistics is derived.

Validation of the Rheumatic Disease Comorbidity Index [PDF]

open access: yesArthritis Care & Research, 2015
ObjectiveThere is no consensus on which comorbidity index is optimal for rheumatic health outcomes research. We compared a new Rheumatic Disease Comorbidity Index (RDCI) with the Charlson‐Deyo Index (CDI), Functional Comorbidity Index (FCI), Elixhauser Total Score (ETS), Elixhauser Point System (EPS), and a simple comorbidity count (COUNT) using a US ...

Clinical Characteristics and Prognostic Risk Factors for Pediatric B‐Cell Lymphoblastic Lymphoma: A Multicenter Retrospective Cohort Study for China Net Childhood Lymphoma

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background B‐cell lymphoblastic lymphoma (B‐LBL) represents a rare variety of non‐Hodgkin lymphoma, with limited research on its biology, progression, and management. Methods A retrospective analysis was performed on the clinical characteristics of 256 patients aged ≤18 years who received treatment under the China Net Childhood Lymphoma (CNCL)‐
