Patent ID: 7809729

Claim:
A method for updating statistical data models in a model repository organized into three levels including a project level, a diagram level, and a model level, the model repository having one or more index structures, each index structure including one or more attributes associated with the statistical data models, the one or more attributes describing statistical data model components contained within the statistical data models, the method comprising: receiving, using one or more processors, a statistical data model; and updating, using the one or more processors, a model repository index structure such that: when updating a main-type index structure, a new record is created and appended to the main-type index structure, the new record including the one or more model attributes, a model folder name, and an export time, and when updating a tree-type index structure, a list is created using any splitting variables associated with the model, wherein a splitting variable is a predictor variable, wherein a predictor variable defines a group within a tree-type index structure, and wherein a new record is created and appended to the tree-type index structure, the new record including a model tree path name and the first splitting variable on the splitting variable list.
