An Invariant-Sum Characterization of Benford's Law
نویسنده
چکیده
The accountant Nigrini remarked that in tables of data distributed according to Benford s Law the sum of all elements with rst digit d d is approxi mately constant In this note a mathematical formulation of Nigrini s observation is given and it is shown that Benford s Law is the unique probability distribution such that the expected sum of all elements with rst digits d dk is constant for every xed k

Shift Invariant Spaces and Shift Preserving Operators on Locally Compact Abelian Groups
We investigate shift invariant subspaces of $L^2(G)$, where $G$ is a locally compact abelian group. We show that every shift invariant space can be decomposed as an orthogonal sum of spaces each of which is generated by a single function whose shifts form a Parseval frame. For a second countable locally compact abelian group $G$ we prove a useful Hilbert space isomorphism, introduce range funct...

متن کاملBenford’s Law: Textbook Exercises and Multiple-Choice Testbanks
Benford's Law describes the finding that the distribution of leading (or leftmost) digits of innumerable datasets follows a well-defined logarithmic trend, rather than an intuitive uniformity. In practice this means that the most common leading digit is 1, with an expected frequency of 30.1%, and the least common is 9, with an expected frequency of 4.6%. Currently, the most common application o...
متن کاملBiological pathway kinetic rate constants are scale-invariant
MOTIVATION Scale-free networks have had a profound impact in Biology. Network theory is now used routinely to visualize, navigate through, and help understand gene networks, protein-protein interactions, regulatory networks and metabolic pathways. Here we analyse the numerical rather than topological properties of biological networks and focus on the study of kinetic rate constants within pathw...
متن کاملAnalysis of Top 500 Central and East European Companies Net Income Using Benford's Law
There are numerous useful methods that can be conducted in data analysis in order to check data correctness and authenticity. One of contemporary and efficient methods is application of so-called Benford's Law. In this paper we examine ways of application of this law in investigation of specific net income number set. Our aim is to make a conclusion if this number set conforms to Benford's Law....
