Reference excerpt

Roger Lee Berger is an American statistician and professor, co-author of Statistical Inference, first published in 1990 with collaborator George Casella.

Early life and education Roger Lee Berger was born August 21, 1951, in rural northwest Kansas. His early interest in mathematics ripened as he attended the University of Kansas, switching from physics to mathematics with emphasis on real analysis as an undergraduate. Graduating in 1973, he studied graduate statistics at Purdue University, earning a master's degree in 1975 and a doctorate in 1977. Building on the work of his advisor Shanti S. Gupta in subset selection, Berger wrote Minimax, Admissible, and Gamma-Minimax Multiple Decision Rules to complete his doctoral studies.

University career and research Berger's first professor appointment was at Florida State University in 1977. Later, he served at North Carolina State University and then Arizona State University, where he retired in 2017. Throughout his career, he supervised eleven students in statistics on topics ranging from theory, such as exact hypothesis testing, more powerful tests with linear and elliptical constraints, to applied biostatistics. In 2003, Purdue deemed Berger a Distinguished Alumnus.

Friendship and collaboration with George Casella Berger and George Casella met at Purdue and became fast friends, studying statistics together. In 1983 at the Eastern North American Region (ENAR) conference of the International Biometric Society, Casella asked Berger to co-author a new master's level introductory text to statistical inference, hoping to revise and improve Hogg and Craig's Introduction to Mathematical Statistics. This led to the publication of Statistical Inference in 1990. They continued to publish papers together, touching on topics such as generalized means and the reconciliation of Bayesian and frequentist testing, until Casella's death in 2012.

Worked examples

Example 1 — a first encounter with Roger Lee Berger

Start with the simplest possible case. Write down what Roger Lee Berger claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Roger Lee Berger before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Roger Lee Berger ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Roger Lee Berger

In research: Roger Lee Berger appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Roger Lee Berger in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Roger Lee Berger is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1951 births, 20th-century American statisticians, 21st-century American statisticians, so understanding it makes those chapters shorter.
In everyday life: Look for Roger Lee Berger outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
