what is the value to discredit a model how does the cumulative lift curve differ in a model how is data mining stability measured? when should uncertainty discredit a model why isn't the first model better than the second when is the model instability what is the standard deviation for a second model what does it mean when model instability is large enough to discredit the model? what is meant standard error of a sas model difference between first and second model which is better, first or second model in terms of stability or indeterminacy? average standard error in a model discredit what's the difference between the first and second model? why is the average standard error larger than the second model? what is model instability what is the mean standard error of the second model? what model is unstable? what is the standard deviation of a model what is the mean standard error for a model why the uncertainty curve on sas test datasets is important
