 (then the "State University of Iowa"). However, Hogg studied statistics under Allen Craig, who became his mentor and helped him obtain a job teaching statistics at the Mathematics Department. Hogg earned his Ph.D. 1950 under Allen Craig. After graduating, Hogg remained at the Mathematics Department, where he remained to become a long-serving professor.

Collaboration and friendship with Allen Craig

The textbook "Hogg and Craig" was innovative, particularly in emphasizing sufficient statistics: Sufficient statistics were treated not only for parametric families
Exponential family
In probability and statistics, an exponential family is an important class of probability distributions sharing a certain form, specified below. This special form is chosen for mathematical convenience, on account of some useful algebraic properties, as well as for generality, as exponential...

Completeness (statistics)
In statistics, completeness is a property of a statistic in relation to a model for a set of observed data. In essence, it is a condition which ensures that the parameters of the probability distribution representing the model can all be estimated on the basis of the statistic: it ensures that the...

As noted before, Craig was Hogg's mentor, helping him to obtain a teaching position while a graduate student and also supervising his thesis. Later, after Hogg had graduated, Craig became a close friend, and served as the best man at Hogg's wedding and later as the "godparent

Chairing a new Department of Statistics

In 1965 Hogg became the founding chair of the new Department of Statistics and Actuarial Science, and he remained as the chair for nineteen years. At Iowa, Hogg held other positions, including Chair of the Quality Management and Productivity Program and the Hanson Chair of Manufacturing Productivity. After serving 51 years as an instructor at the University of Iowa, Hogg became Professor Emeritus in 2001.
