Congression – A fast regression technique with a great number of functions of all predictors.

The term Congression is used for an entirely new technique for Multiple Regression Analysis. The merits of the new technique are obvious. It is made possible to introduce a vast number of derived predictors in the analysis without prolonging the computing time.

In the examples given in the paper, 6 predictors are increased to 1068, and the analysis carried out in less than 25 per cent of the time now needed for 6 predictors.

The main features of Congression are the Grouping of data in Parties and the use of Grouping Diagrams as an interface towards a great number of pre-prepared. Potential functions of any two predictors; xi2, xixj, sin x1 and V xi2 + xj2 , are examples of such functions.
