Data analysis often involves finding models that can explain patterns in data, and reduce possibly large data sets to more compact model‐based representations. In Statistics, many methods are available to compute model information. Among others, regression models are widely used to explain data. However, regression analysis typically searches for the best model based on the global distribution of data. On the other hand, a data set may be partitioned into subsets, each requiring individual models. While automatic data subsetting methods exist, these often require parameters or domain knowledge to work with. We propose a system for visual‐interactive regression analysis for scatter plot data, supporting both global and local regression modeling. We introduce a novel regression lens concept, allowing a user to interactively select a portion of data, on which regression analysis is run in interactive time. The lens gives encompassing visual feedback on the quality of candidate models as it is interactively navigated across the input data. While our regression lens can be used for fully interactive modeling, we also provide user guidance suggesting appropriate models and data subsets, by means of regression quality scores. We show, by means of use cases, that our regression lens is an effective tool for user‐driven regression modeling and supports model understanding.
A fifth order shear deformation theory considering transverse shear deformation effect is presented for displacement in propped cantilever beam. The considered displacement field accounts for non-linear variation corresponding to depth of beam. Governing equations and boundary conditions of the theory are obtained using the standard of virtual work. Numerical results for static deflection analysis for aspect ratio (length to depth) 2 to 50 for isotropic beam is obtained. The results of present theory are in close agreement with those of higher order shear deformation theories.
Background CAPOS syndrome (cerebellar ataxia, areflexia, pescavus, optic atrophy, and sensorineural hearing loss) is a rare congenital autosomal dominant disorder. The resulting neurological sequelae of impairments are progressive in nature and may interfere with functional independence, performing activities of daily living (ADL’s), and subsequently, affecting the quality of life (QOL). Since it is an extremely rare disorder, there is a severe dearth in the literature about how specific physiotherapy interventions may affect their functional status. Therefore, our objective was to investigate the effects of proprioceptive neuromuscular facilitation (PNF) and Frenkel’s coordination exercises on functional recovery in a patient with CAPOS syndrome. Case presentation We herein present a case of a 25-year-old Indian male with complaints of generalized body weakness, difficulty visualizing distant objects, nystagmus, progressive sensorineural deafness, and ataxia. He was rehabilitated with a structured/customized physiotherapy protocol consisting of PNF approach and coordination exercises for 4 weeks, 6 days/week, 60 min daily. An improvement in overall functional performance of patient as per post-intervention scores of manual muscle testing, trunk control measurement scale, functional independence measure (components of self-care, transfers, and locomotion), and decline in severity of ataxia on scale for assessment and rating of ataxia scale was observed. Conclusion PNF and Frenkel’s exercises resulted in an improvement in overall functional performance of the patient. Improvement was observed in post-test scores of Manual Muscle Testing (MMT), Trunk Control Measurement Scale (TCMS), and Functional Independence Measure (FIM) for the components of self-care, transfers, and locomotion. Additionally, results also showed a decline in severity of ataxia on post-test scores of scale for the assessment and rating of ataxia (SARA) scale (i.e., from severe to moderate).
