Abstract: Methods and apparatuses are disclosed that create prediction models. Embodiments of the methods involve various elements such as sampling representative data, detecting statistical faults in the data, inferring missing values in the data set, and eliminating independent variables. Methods and apparatuses are also disclosed that train analysts to create prediction models. Embodiments of these methods involve providing operational component selections to the user, receiving operational and configuration selections, and displaying the result of applying the operational components and selections to representative data.
