Pathophysiology of Multiple Sclerosis Multiple sclerosis (MS) is a chronic inflammatory autoimmune demyelinating disease of the central nervous system‚ affecting the brain and spinal cord. MS affects approximately 400‚000 people in the United States alone. The onset of MS is usually between 20 and 40 years of age and is more common in women; men may have a more severe progressive course (Luzzio‚ 2013).

Artificial Intelligence Artificial Intelligence is playing an important role in today’s world and in the future. “Evidence of Artificial Intelligence folklore can be trace back to Egypt‚ but with the development of the electronic computer in 1941‚ the technology finally became available to create machine intelligence. Its short modern history‚ advancements in the field of AI have been slower than first estimated‚ progress continued to be made. From its birth 4 decades ago‚ there have been a variety

Multiple regression‚ a time-honored technique going back to Pearson’s 1908 use of it‚ is employed to account for (predict) the variance in an interval dependent‚ based on linear combinations of interval‚ dichotomous‚ or dummy independent variables. Multiple regression can establish that a set of independent variables explains a proportion of the variance in a dependent variable at a significant level (through a significance test of R2)‚ and can establish the relative predictive importance
