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.
Vascular loop syndrome. 1  A 50 y o male with typical left hemi facial spasm. 2  Routine MRI axial T2w sequences were absolutely normal except tortuous vertebro basilar with marked tortuousity of left sided vertebral. 3  Imaging diagnosis: Vascular loop syndrome with 7th - 8th CN Compression, Hemifacial spasm. Vascular loop syndrome. Abnormal anatomical variation or course of vessel causing symptomatic compression over cranial nerves at IAC or Cp Angle cistern. Spasmodic hyperfunction of nerve due to compression. Compression of 5th CN (Trigeminal nerve) present with trigeminal neuralgia and 7th CN (Facial nerve) present with hemi facial spasm.
