Observation that in many real-life datasets, the leading digit is likely to be small For the unrelated adage, see Benford's law of controversy. The distribution of first digits, according to Benford's law. Each bar represents a digit, and the height of the bar is the percentage of ...
Benford's law : In many collections of data, a given data point has roughly a 30% chance of starting with the digit 1. Benford's law of controversy: Passion is inversely proportional to the amount of real information available. Bennett's laws are principles in quantum information theory. Named for Charles H. Bennett.
Hill discovered what many consider to be the definitive proof of Benford's law. [1] [2] He is also known for his research in the theories of optimal stopping (including secretary problems and prophet inequality problems) and of fair division, in particular the Hill-Beck land division problem.
Also called resource cost advantage. The ability of a party (whether an individual, firm, or country) to produce a greater quantity of a good, product, or service than competitors using the same amount of resources. absorption The total demand for all final marketed goods and services by all economic agents resident in an economy, regardless of the origin of the goods and services themselves ...
In the 1980s and 1990s endogenous growth theory arose to challenge the neoclassical growth theory of Ramsey and Solow. This group of models explains economic growth through factors such as increasing returns to scale for capital and learning-by-doing that are endogenously determined instead of the exogenous technological improvement used to ...
Benford's law, named after physicist Frank Benford, who stated it in 1938, although it had been previously stated by Simon Newcomb in 1881. Bertrand's ballot theorem proved using André's reflection method, which states the probability that the winning candidate in an election stays in the lead throughout the count.
A third set, referred to as the "neoclassical revival", expanded the definition of capital in exogenous growth theory to include human capital. [179] This strain of research began with Mankiw, Romer, and Weil (1992), [ac] which showed that 78% of the cross-country variance in growth could be explained by a Solow model augmented with human ...
In mathematical statistics, the concept has been formalized as the Zipfian distribution: A family of related discrete probability distributions whose rank-frequency distribution is an inverse power law relation. They are related to Benford's law and the Pareto distribution. Some sets of time-dependent empirical data deviate somewhat from Zipf's ...
