WebbDescription. modelCalibrationPlot (lgdModel,data) returns a scatter plot of observed vs. predicted loss given default (LGD) data with a linear fit. modelCalibrationPlot supports comparison against a reference model. By default, modelCalibrationPlot plots in the LGD scale. modelCalibrationPlot ( ___,Name,Value) specifies options using one or ... WebbPredictive analytics is often defined as predicting at a more detailed level of granularity, i.e., generating predictive scores (probabilities) for each individual organizational element. This distinguishes it from forecasting. For example, "Predictive analytics—Technology that learns from experience (data) to predict the future behavior of ...

Webbfor the logistic regression model is DEV = −2 Xn i=1 [Y i log(ˆπ i)+(1−Y i)log(1−πˆ i)], where πˆ i is the fitted values for the ith observation. The smaller the deviance, the closer the fitted value is to the saturated model. The larger the deviance, the poorer the fit.
