Introduction to bivariate analysis. â¢ When one measurement is made on each observation, univariate. analysis is applied. If more than one measurement is made on each observation, multivariate analysis is applied. In this section, we focus on bivariate analysis, where exactly two. measurements are made on each observation. The two measurements will be called X and Y . Since X and Y. are obtained for each observation, the data for one observation. is the pair (X,Y ).
Also known as: Stasis syndrome and Stagnant loop syndrome. Blind loop syndrome occurs when digested food slows or stops moving through part of the intestines. This causes an overgrowth of bacteria in the intestines. It also leads to problems absorbing nutrients. The name of this condition refers to the blind loop formed by part of the intestine that is bypassed.
From Wikipedia, the free encyclopedia. Neuromyelitis optica (NMO), also known as Devic's disease or Devic's syndrome, is a heterogeneous condition consisting of the simultaneous inflammation and demyelination of the optic nerve (optic neuritis) and the spinal cord (myelitis). It can be monophasic or recurrent.pinal cord lesions lead to varying degrees of weakness or paralysis in the legs or arms, loss of sensation (including blindness), and/or bladder and bowel dysfunction. Devic's disease is now studied along a collection of similar diseases called Neuromyelitis optica spectrum diseases.
