Abstract: A dynamic computational environment may create, in response to user input, a plurality of mathematical expressions. In the dynamic computational environment, a change made to any one of the plurality of mathematical expressions will be propagated to all of the mathematical expressions, such that each of the plurality of mathematical expressions affected by the change is updated.

Abstract: A dynamic computational environment may create, in response to user input, a plurality of mathematical expressions. In the dynamic computational environment, a change made to any one of the plurality of mathematical expressions will be propagated to all of the mathematical expressions, such that each of the plurality of mathematical expressions affected by the change is updated. In response to user input, one or more of the plurality of mathematical expressions may be selected to form a selected set of mathematical expressions. Propagation of changes into the selected set of mathematical expressions may be blocked.

Abstract: System and methods are provided for applying a dimensionality reduction process to a data set. The method includes obtaining a data set including a first set of variables and identifying collections of the first set of variables for replacement by a second set of variables. The method also includes replacing the collections of the first set of variables with the second set of variables and eliminating the first set of variables from the data set.

Abstract: A method is provided for identifying and communicating a health risk to an individual. The method may include obtaining health information for an individual and predicting, based on the health information, a risk of the individual contracting a disease. The method may also include calculating a rate of change of the risk and calculating a forecasted risk based on the rate of change. Further, the method may include initiating a present action when the forecasted risk is above a first predetermined threshold at a future time.
