The effect of imputed values on the distribution of the goodness-of-fit chi-square statistic
(Elsevier, 1987)
A method used to compensate for nonresponse is to impute missing values; that is, to replace each missing value with a respondent value selected from all observed values or from a subset of observed values. The imputation ...
Characterization of optima in smooth Pareto economic systems
(Elsevier, 1975)
Simple techniques of calculus and geometry are used to study and characterize the optima of pure exchange economies in which the utility functions are smooth but not necessarily convex. It is also shown how one can reduce ...
The choice of a log-linear model using a Cp-type statistic
(Elsevier, 1984-08)
Most methods of selecting an appropriate log-linear model for categorical data are sensitive to the underlying distributional assumptions. However, there are many situations in which the assumption that the data are randomly ...
Modeling and analyzing HIV transmission: the effect of contact patterns
(Elsevier, 1988-12)
A compartmental model is presented for the spread of HIV in a homosexual population divided into subgroups by degree of sexual activity. The model includes constant recruitment rates for the susceptibles in the subgroups. ...
STORIES OF AGENCY: DO GRADUATE STUDENTS PERCEIVE THEMSELVES AS PART OF THE MATHEMATICAL COMMUNITY?
(Hoosier Association of Mathematics Teacher Educators., 2017-10-08)
Graduate student teaching assistants (GTAs) are responsible for the instruction of undergraduate students in critical introductory courses, but are not yet in the position of professors. Given their unique status, we ask ...
Counting Groves-Ledyard equilibria via degree theory
(Elsevier, 1983-10)
We study the Groves-Ledyard mechanism for determining optimal amounts of public goods in economies whose agents have the most general class of preferences for which a Pareto amount of public goods can be computed independently ...
On the unique satisfiability problem
(Elsevier, 1982)
UNIQUE SAT is the problem of deciding whether a given Boolean formula has exactly one satisfying truth assignment. This problem is a typical (moreover complete) representative of a natural class of problems about unique ...
