Audience Diversion Due to Cable Television: An Application of Nonlinear, Nondiagonally Weighted, Generalized Least Squares

摘要

A model of television audience shares is estimated and applied to simulate the effect of cable TV carrying distant signals on local stations' audience shares. The model is nonlinear, with a complex error covariance matrix; transformations are used to obtain generalized least squares estimates using an ordinary nonlinear regression package. The conclusion: TV broadcasting will continue to prosper, despite increasing competition from cable. (Author)
