Some Modifications to Calculate Regression Coefficients in Multiple Linear Regression

In a multiple linear regression model, there are instances where one has to update the regression parameters. In such models as new data become available, by adding one row to the design matrix, the least-squares estimates for the parameters must be updated to reflect the impact of the new data. We will modify two existing methods of calculating regression coefficients in multiple linear regres...

MISQP: A Fortran Subroutine of a Trust Region SQP Algorithm for Mixed-Integer Nonlinear Programming

The Fortran subroutine MISQP solves mixed-integer nonlinear programming problems by a modified sequential quadratic programming (SQP) method. Under the assumption that integer variables have a smooth influence on the model functions, i.e., that function values do not change drastically when inor decrementing an integer value, successive quadratic approximations are applied. The algorithm is sta...

CAVAP, A FORTRAN SUBROUTINE FOR SOLVING AN ASSIGNMENT PROBLEM WITH CONCAVE OBJECTIVE by

This document describes a FORTRAN IV subroutine named CAVAP (an acronym for conCAVe Assignment Problem) which uses a branch and bound method to solve a variant of the assignment problem in which the objective to be minimized is concave. It is assumed that m tasks are to be performed and n different kinds of machines have been defined for possible use in performing them. In general a task may be...
