Measuring Productivity Dispersion [PDF]
SSRN Electronic Journal, 2017 Abstract Measuring the dispersion of productivity or efficiency across firms in a market or industry is rife with methodological issues. Nevertheless, the existence of considerable dispersion now is well documented and widely accepted. Less well understood are the economic features and mechanisms underlying the magnitude of dispersion

One-Way and Two-Way ANOVA: Inferences About a Robust, Heteroscedastic Measure of Effect Size
Methodology, 2022 Consider a one-way or two-way ANOVA design. Typically, groups are compared based on some measure of location. The paper suggests alternative methods where measures of location are replaced by a robust measure of effect size that is based in part on a ...

DECAMETER PULSAR/TRANSIENT SURVEY OF NORTHERN SKY. PARAMETERS OF INDIVIDUAL PULSES
Radio Physics and Radio Astronomy, 2017 Purpose: Studying individual burst characteristics recorded by the UTR-2 radio telescope UTR-2 during the Decameter pulsar/transient survey of northern sky, based on the analysis of 70 % of primary data. Design/methodology/approach: Individual pulses,

A fast radio burst with a low dispersion measure [PDF]
, 2018 Fast radio bursts (FRBs) are millisecond pulses of radio emission of seemingly extragalactic origin. More than 50 FRBs have now been detected, with only one seen to repeat.

Histogram lies about distribution shape and Pearson's coefficient of variation lies about relative variability [PDF]
Tutorials in Quantitative Methods for Psychology, 2022 Histograms and Pearson's coefficient of variation are among the most popular summary statistics. Researchers use histograms to judge the shape of quantitative data distribution by visual inspection.

The Mean and Scatter of the Velocity Dispersion-Optical Richness Relation for maxBCG Galaxy Clusters [PDF]
, 2007 The distribution of galaxies in position and velocity around the centers of galaxy clusters encodes important information about cluster mass and structure. Using the maxBCG galaxy cluster catalog identified from imaging data obtained in the Sloan Digital

Measurement of QT dispersion [PDF]
Heart, 1998 In 1985, Mirvis1 reported on a significant spatial variation in QT intervals in normal individuals and patients with acute myocardial infarction. More recently, there has been an increasing interest in what has become known as QT dispersion, which is defined as the difference between the maximum and minimum QT interval of the 12 lead ECG.2 A number of ...

Dispersion measures as immunization risk measures [PDF]
, 2002 The quadratic and linear cash flow dispersion measures M2 and Ñ are two immunization risk measures designed to build immunized bond portfolios. This paper generalizes these two measures by showing that any dispersion measure is an immunization risk ...
