Log-normal distribution from a process that is not multiplicative but is additive
, 2013 The central limit theorem ensures that a sum of random variables tends to a Gaussian distribution as their total number tends to infinity. However, for a class of positive random variables, we find that the sum tends faster to a log-normal distribution ...

Elements for Response Time Statistics in ERP Transaction Systems
, 2005 We present some measurements and ideas for response time statistics in ERP systems. It is shown that the response time distribution of a given transaction in a given system is generically a log-normal distribution or, in some situations, a sum of two or ...

A study of the Mg II 2796.34 A emission line in late--type normal, and RS CVn stars [PDF]
, 2003 We carry out an analysis of the Mg II 2796.34 A emission line in RS CVn stars and make a comparison with the normal stars studied in a previous paper (Paper I).

Generalized Log-Normal Chain-Ladder
, 2018 We propose an asymptotic theory for distribution forecasting from the log normal chain-ladder model. The theory overcomes the difficulty of convoluting log normal variables and takes estimation error into account. The results differ from that of the over-

Using a Log-normal Failure Rate Distribution for Worst Case Bound Reliability Prediction [PDF]
, 2003 Prior research has suggested that the failure rates of faults follow a log normal distribution. We propose a specific model where distributions close to a log normal arise naturally from the program structure.

Log-normal distribution based EMOS models for probabilistic wind speed forecasting [PDF]
, 2014 Ensembles of forecasts are obtained from multiple runs of numerical weather forecasting models with different initial conditions and typically employed to account for forecast uncertainties.

Asian Option Pricing with Orthogonal Polynomials
, 2018 In this paper we derive a series expansion for the price of a continuously sampled arithmetic Asian option in the Black-Scholes setting. The expansion is based on polynomials that are orthogonal with respect to the log-normal distribution.

Runaway Events Dominate the Heavy Tail of Citation Distributions [PDF]
, 2012 Statistical distributions with heavy tails are ubiquitous in natural and social phenomena. Since the entries in heavy tail have disproportional significance, the knowledge of its exact shape is very important.

Fluctuations of the Bose-Einstein condensate [PDF]
, 2014 This article gives a rigorous analysis of the fluctuations of the Bose-Einstein condensate for a system of non-interacting bosons in an arbitrary potential, assuming that the system is governed by the canonical ensemble.
