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 ).
Dr Matt A. Morgan â et al. Blind loop syndrome (or blind pouch syndrome) is an event that may occur after an end-to-end or end-to-side bowel anastomosis. Dilatation and stasis of the bypassed bowel may lead to bacterial overgrowth, breakdown of bile salts, and result in nutritional problems. It may even eventually lead to mucosal ulceration.
Parinaud's Syndrome, also known as dorsal midbrain syndrome is a group of abnormalities of eye movement and pupil dysfunction. It is caused by lesions of the upper brain stem and is named for Henri Parinaud (1844â1905), considered to be the father of French ophthalmology. Parinaud's Syndrome is a cluster of abnormalities of eye movement and pupil dysfunction, characterized by: 1. Paralysis of upgaze: Downward gaze is usually preserved. This vertical palsy is supranuclear, so doll's head maneuver should elevate the eyes, but eventually all upward gaze mechanisms fail. 2. Pseudo-Argyll Robertson pupils: Accommodative paresis ensues, and pupils become mid-dilated and show light-near dissociation.
