An econometric model of the canned tuna market is used to evaluate biased and unbiased estimators. Four methods for improving mean square error when multicollinearity is present in a regression equation are examined and compared with the results of ordinary least squares (OLS). Exact and inexact prior information methods are...
Linear programming is now widely accepted and used by researchers and industrial management people, but its adoption by farm managers has been slow. This study concentrates on the development of improved data transmittal techniques for farm organization linear programming. The program model is designed to analyze crop production alternatives. Models...
Questionnaires were mailed to farmers in six counties of the
Willamette Valley requesting the kind and size of enterprises and the
gross income received from the enterprises on each farm.
Enterprises were defined both as general livestock or crop categories
and as individual crop or livestock enterprises. Two computer
programs...
An obstruction theory is developed for "simplicial
bundles" which are generalized fiber bundles (over a
simplicial complex). Cross sections of one of the examples
of a simplicial bundle given (the Lefschetz bundle) are
essentially fixed point free maps of the base space.
In this dissertation we construct a homology spectral sequence
attached to a submersion whose E² term takes values in a certain
homology with local coefficients. The motivation for this work is
that the spectral sequence provides an effective tool for the conjecture
and proof of theorems regarding the global structure...
In this dissertation we construct a homology theory on the category of submersions which generalizes the homology of the base space with coefficients in the homology of the fiber as given by the E²-terms of the Serre spectral sequence of a fiber bundle. The main motivation for this new homology...
