What is the purpose of MDS?
The MDS is influential tool for executing standardized assessments and promoting care management in the nursing homes as well as non-critical hospital shakers (SB). Its contents have an impact on researchers, providers, families, residents and decision makers, and everyone is concerned about the reliability, effectiveness and relevance of MDS (Deshmukh, 2014).
The objectives are:
• Advance neuroscience related to dyskinesia
• Improve patient diagnosis and treatment; operate specifically for scientific, educational and academic purposes
• Share thoughts and advance relevant scientific and clinical disciplines
• Inspire health care and related professionals and scientists to participate in the activities of the association
• Collaborate with other relevant professional and non-professional organizations
What is a perceptual map?
Perceptual maps are graphs that market researchers and companies use to depict and comprehend what the target customer feels and thinks about a specific product or brand.

It is a graphical process used to represent the output of the hierarchical clustering technique. A dendrogram is strictly described as the binary tree with distinct root with whole data items like its leaves. Usually, all leaves are displayed at the similar level of...
