Jana Jurečková

Jana Jurečková is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Jana Jurečková rather than just read about it. In short: Jana Jurečková (née Přistoupilová, born 20 September 1940) is a Czech statistician, known for her work on rankings, robust statistics, outliers and tails, asymptotic theory, and the behavior of statistical estimates for finite sample sizes. Education and career Jurečková was born in Prague and grew up in Roudnice nad Labem.

Key takeaways

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

Reference excerpt

Jana Jurečková (née Přistoupilová, born 20 September 1940) is a Czech statistician, known for her work on rankings, robust statistics, outliers and tails, asymptotic theory, and the behavior of statistical estimates for finite sample sizes.

Education and career Jurečková was born in Prague and grew up in Roudnice nad Labem. She earned a master's degree from Charles University, and completed her Ph.D. in 1967 from the Czechoslovak Academy of Sciences under the supervision of Jaroslav Hájek. She completed a habilitation in 1982 and a Dr.Sc. in 1984. She joined Charles University in 1964, becoming part of the Department of Probability and Mathematical Statistics in the Faculty of Mathematics and Physics, and has also been associated with the Jaroslav Hájek Center for Theoretical and Applied Statistics at Masaryk University.

Books She is the author of Robust Statistical Procedures: Asymptotics and Interrelations (with Pranab K. Sen, Wiley, 1996), of Adaptive Regression (with Yadolah Dodge, Springer, 2000), of Robust Statistical Methods with R (with Jan Picek, Chapman & Hall/CRC, 2005), and of a textbook on robust statistics in Czech.

Recognition She is a Fellow of the Institute of Mathematical Statistics an elected member of the International Statistical Institute, and since 2003 a member of the Learned Society of the Czech Republic.

Worked examples

Example 1 — a first encounter with Jana Jurečková

Start with the simplest possible case. Write down what Jana Jurečková 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 Jana Jurečková 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 Jana Jurečková 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 Jana Jurečková

In research: Jana Jurečková 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 Jana Jurečková 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: Jana Jurečková is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940 births, Academic staff of Charles University, Charles University alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Jana Jurečková 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.
