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.
A causal loop diagram (CLD) is a causal diagram that aids in visualizing how different variables in a system are interrelated. The diagram consists of a set of nodes and edges.Nodes represent the variables and edges are the links that represent a connection or a relation between the two variables. negative causal link means the two nodes change in opposite directions, i.e. if the node in which the link starts increases, the other node decreases and vice versa. Closed cycles in the diagram are very important features of the CLDs. A closed cycle is either defined as a reinforcing or balancing loop.
