Solvers in logistic regression

WebOne major assumption of Logistic Regression is that each observation provides equal information. Analytic Solver Data Mining offers an opportunity to provide a Weight variable. Using a Weight variable allows the user to allocate a weight to each record. A record with a large weight will influence the model more than a record with a smaller weight.
