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.
Vestibular paroxysmia. Vestibular paroxysmia is also referred to as disabling positional vertigo, vascular loop syndrome or microvascular compression syndrome in the literature. Other vascular compression syndromes include trigeminal neuralgia and hemifacial spasm. Vestibular paroxysmia is a controversial syndrome. It is believed that a blood vessel, which forms a loop around the vestibular branch of the cochleovestibular nerve (VIII cranial nerve) is responsible.
