BACKGROUND This cross validation study examined the reliability of the Multidimensional Pain Inventory (MPI) and the stability of the Multidimensional Pain Inventory Classification System of the empirically derived subgroup classification obtained by cluster analysis in chronic musculoskeletal pain. Reliability of the German Multidimensional Pain Inventory was only examined once in the past in ...

New application areas for databases like data warehousing and OLAP (Online Analytical Processing) deploy the multidimensional data model in order to describe the application domain. Consequently, OLAP systems are represented by a multidimensional database schema to adequately reflect the application semantics. FIESTA presents a methodology for the evolution of such multidimensional schemas. Cor...

Multidimensional analysis and online analytical processing (OLAP) operations require summary information on multidimensional data sets. Most common are aggregate operations along one or more dimensions of numerical data values. Simultaneous calculation of multidimensional aggregates are provided by the Data Cube operator, used to calculate and store summary information on a number of dimensions...

The amount of data that our digital society collects is unprecedented. This represents a valuable opportunity to improve our quality of life by gaining insights about complex problems related to neuroscience, medicine and biology among others. Topological methods, in combination with classical statistical ones, have proven to be a precious resource in understanding and visualizing data. Multidi...

Multidimensional access methods are considered to be a promising approach for providing acceptable performance to analysis-centric applications. However, despite the large body of research work in this field, the commercial support for multidimensional indexes is still very weak. The reason for this discrepancy is threefold: first, no standard multidimensional index like the B-Tree for one-dime...

OBJECTIVES To identify the chronic health conditions associated with multidimensional poverty. DESIGN Cross-sectional study of the nationally representative Survey of Disability, Ageing and Carers, conducted by the Australian Bureau of Statistics. SETTING Australian population in 2003. PARTICIPANTS 35 704 individuals randomly selected from the Australian population by the Australian Burea...

ÐCurrent data repositories include a variety of data types, including audio, images, and time series. State-of-the-art techniques for indexing such data and doing query processing rely on a transformation of data elements into points in a multidimensional feature space. Indexing and query processing then take place in the feature space. In this paper, we study algorithms for finding relationshi...

background and objectives: this study aimed to validate the west haven-yale multidimensional pain inventory (whympi) for iranian patients with chronic pain. methods: 585 patients with chronic pain in legs, back, hands, neck and shoulders were entered into this study. the west haven-yale multidimensional pain inventory (whympi) was used for assessment of pain in these patients. for validation of...
