Key takeaways

Sharon Xiangwen Xie belongs to mathematics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Sharon Xiangwen Xie to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Sharon Xiangwen Xie from memory before moving on to harder problems.

Reference excerpt

Sharon Xiangwen Xie is a Chinese biostatistician and epidemiologist who studies neurodegenerative diseases. She is a professor of biostatistics in the Department of Biostatistics, Epidemiology, and Informatics at the University of Pennsylvania.

Education Xie earned a bachelor's degree in applied mathematics from Beijing University of Technology in 1991. She then attended the University of Texas, where she completed a master's degree in statistics in 1993. After that, she moved to the University of Washington, where she earned a second master's degree in biostatistics in 1995 and a Ph.D. in 1997. Her dissertation, Covariate Measurement Error Methods In Failure Time Regression, was supervised by Ross L. Prentice.

Career Xie was elected a Fellow of the American Statistical Association in 2018. She serves as program chair for the Biometrics Section of the American Statistical Association at the 2019 Joint Statistical Meetings. In 2021, she was elected secretary of the ASA Lifetime Data Science Section.

Worked examples

Example 1 — a first encounter with Sharon Xiangwen Xie

Start with the simplest possible case. Write down what Sharon Xiangwen Xie 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 Sharon Xiangwen Xie 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 Sharon Xiangwen Xie 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 Sharon Xiangwen Xie

In research: Sharon Xiangwen Xie 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 Sharon Xiangwen Xie 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: Sharon Xiangwen Xie is common in secondary-school and first-year university syllabi. It links to neighbouring topics American statisticians, Biostatisticians, Chinese statisticians, so understanding it makes those chapters shorter.
In everyday life: Look for Sharon Xiangwen Xie 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.
