When working to create a logistic regression model, an analyst is considering two models: Model 1 includes only one predicting variable A. Model 2 includes variable A in addition to predicting variable B. The analyst notices that the sign of the estimated coefficient for A is negative in model 1 and positive in model 2. This is most likely because:
