Frankie notices that her binary response model works nearly perfectly with the data she used to build the model. However, she is worried that this model will not perform as well with data outside of the estimation sample. What technique should she use to assess the predictive power of her model? Multiple Choice O mean squared error (MSE) model-validation cross-validation the coefficient of variation (R2)
