In the world of investing, robust is a characteristic describing a model's, test's, or system's ability to perform effectively while its variables or assumptions are altered. It focuses on the more typical role of adaptation as a means of coping with uncertainties in the system model. Predictive modeling is a process that forecasts outcomes and probabilities through the use of data mining.In this, each model is made up of a specific number of predictors, which are variables that help in determining as well as influencing future results. 0000023158 00000 n 0000053844 00000 n 0000079620 00000 n 0000058665 00000 n Raković SV (2009) Set theoretic methods in model predictive control. 0000074175 00000 n 0000003352 00000 n Then, at prediction time, compare each feature's actual value to its predicted value in each of the imputation models predicting it.
