Three Essays on Professional Advising.

Yoon, Kyoung-Soo - 2008

This dissertation considers three topics in professional advising and forecasting. Chapter 1 examines a principal's optimal contracting with experts. In an environment where experts have heterogeneous private signal distributions and type dependent reservation utilities, we show that the...

Variations in the efficiency of a mathematical programming solver according to the order of the constraints in the model

Pastor, Rafael - In: Journal of Industrial Engineering and Management (JIEM) 1 (2008) 2, pp. 4-15

It is well-known that the efficiency of mixed integer linear mathematical programming depends on the model (formulation) used. With the same mathematical programming solver, a given problem can be solved in a brief calculation time using one model but requires a long calculation time using...

Multinomial goodness-of-fit: Large-sample tests with survey design correction and exact tests for small samples

Jann, Ben - In: Stata Journal 8 (2008) 2, pp. 147-169

I introduce the new mgof command to compute distributional tests for discrete (categorical, multinomial) variables. The command supports large-sample tests for complex survey designs and exact tests for small samples as well as classic large-sample Chi^2-approximation tests based on Pearson’s...
