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.
Afferent loop syndrome is a problem that can occur after some kinds of stomach surgery. Itâs also known as afferent limb syndrome. The small intestine loop has two loops. The loop going to the upper stomach is the afferent loop. The loop carrying food away from the stomach is called the efferent loop.
