sciatic nerve

a large peripheral nerve that connects the receptor and effector cells in the leg to the spinal cord. Pain in the leg, which may extend over the entire length of this nerve, from the buttocks to the foot, is called sciatica. The cause is most commonly a slipped disk pressing on the nerve root emerging from the spinal cord.

multiple discriminant analysis

(MDA) a multivariate statistical procedure for examining the relationship between a set of more than two categories representing an outcome variable and a set of predictor variables. It often is used to verify that the predictors (e.g., family history, self-esteem, number of sleeping hours) are accurately classifying individuals into the appropriate categories of the outcome variable (diagnosis of depression). Also called multiple classification analysis (MCA).
