Backcasting from Graduation Targets to Required Enrollments Using the Generalized Inverse of the Transformation Matrix. Program in International Education Finance.
Bezeau, Lawrence M.
The general solution to the problem of calculating school enrollments at time (t-1) necessary to meet predetermined graduation or manpower targets at time (t) is derived and examined. The solution, which is obtained by minimizing the squared discrepancy between the given graduations and those predicted by the enrollments, requires the unique generalized inverse of the transformation matrix that maps enrollments into graduations. Information on the rank and order of this matrix is used to evaluate the indeterminancy and approximateness of the solution. (Author)
