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.
Tethered cord syndrome (TCS) or occult spinal dysraphism sequence refers to a group of neurological disorders that relate to malformations of the spinal cord.Various forms include: 1  Tight filum terminale. 2  Lipomeningomyelocele. 3  Split cord malformations (diastematomyelia). 4  Dermal sinus tracts. 5  Dermoids. 6  Cystoceles. tethered cord, however, is held taut at the end or at some point in the spinal canal. In children, a tethered cord can force the spinal cord to stretch as they grow. In adults the spinal cord stretches in the course of normal activity, usually leading to progressive spinal cord damage if untreated.
