Sigbert Prais

Sigbert Prais is a astronomy 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 Sigbert Prais rather than just read about it. In short: Sigbert Jon Prais, FBA (19 December 1928 – 22 February 2014) was an economist and had been the senior research fellow at the National Institute of Economic and Social Research (NIESR) since 1970. Life On 19 December 1928, Sigbert Jon Prais was born in Frankfurt-am-Main, Germany; he was the oldest of four children to orthodox Jewish parents.

Key takeaways

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

Reference excerpt

Sigbert Jon Prais, FBA (19 December 1928 – 22 February 2014) was an economist and had been the senior research fellow at the National Institute of Economic and Social Research (NIESR) since 1970.

Life On 19 December 1928, Sigbert Jon Prais was born in Frankfurt-am-Main, Germany; he was the oldest of four children to orthodox Jewish parents. His family arrived in Britain in 1934 as Jewish refugees fleeing Nazi oppression in Germany. Prais' father established a manufacturing company that made metal frames and ornaments for women's handbags, in Birmingham. Prais was sent to school in London and later continued his studies at the King Edward's School, Birmingham. From King Edward's School, he matriculated to the University of Birmingham for his undergraduate studies and then moved on to the PhD program at the Department of Applied Economics at Fitzwilliam College, Cambridge. While at Cambridge, Prais collaborated with Hendrik Houtthaker on a study that focused on pre-war household expenditures. In 1955, Prais and Houtthaker's study was published as "Analysis of Family Budgets"; the study would prove to be a foundation for studies in subsequent research. Prais had found great success in the field of economics after having his study published and was quickly asked to be a lecturer at the Fitzwilliam College, Cambridge Department of Applied Economics. In 1953, when Prais was 24 years old, he took up a fellowship at the Cowles Commission for Research in Economics in Chicago. There he made important connections for his career, most notably C. B. Winsten. Together, Prais and Winsten conceived their "Prais–Winsten estimation". They formulated the econometric equation as a modification to the "Cochrane–Orcutt estimation" equation; it is believed to a more efficient formula for estimating the linear model. In 1954, Prais maintained his lecturer position at the Department of Applied Economics at the Fitzwilliam College, Cambridge University while pursuing his career at the National Institute of Economic and Social Research (NIESR) in London. From NIESR, Prais instantly went to work with Peter Hart on research into the growth of Great Britain companies. Prais and Hart's research led to the publication of two important studies on the matter: the first in 1956, titled "The Analysis of Business Concentration: A Statistical Approach", and second in 1976, "The Evolution of Giant Firms in Britain". In the 1960s, Prais left academia and the field of economics for a full decade; he took up work in Birmingham in the industrial trade. He worked at his father's business as the finance director, and led the company to a successful flotation on the London Stock Exchange in 1964. After leaving the family business, Prais decided to re-enter academia and the field of economics. He started back on with NIESR, and at first focused on researching an answer to why Great Britain's industrial performance had seemed to be lagging. He soon came to the conclusion that poor quality education and training were the root of the problem. His growing interests in the study and comparisons of different countries' educational systems and methods came to be internationally renowned. In 1987, Prais' innovative and expert analysis of international educational systems led to his appointment to the Kenneth Baker's mathematics working group. While on the group, Prais campaigned hard to raise the standards of education in Great Britain. In 1985, Prais was elected a fellow to the British Academy. On 22 February 2014, Prais died from colon cancer.

Education Prais was educated at King Edward's School, Birmingham, the University of Birmingham (MCom) and Fitzwilliam College, Cambridge (PhD 1953, ScD 1974).

Worked examples

Example 1 — a first encounter with Sigbert Prais

Start with the simplest possible case. Write down what Sigbert Prais claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Sigbert Prais 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 Sigbert Prais 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 Sigbert Prais

In research
Sigbert Prais appears in astronomy 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 Sigbert Prais 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
Sigbert Prais is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1928 births, 2014 deaths, Academics of the University of Cambridge, so understanding it makes those chapters shorter.
In everyday life
Look for Sigbert Prais 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.
