"... A Bayesian moving average model for correlated count data In this paper we propose a new regression modeling approach for responses that are a correlated time series of counts. The approach is based on a hierarchical Bayesian model that incorporates a latent moving average process with gamma random ..."

COUNTING DATA
, 1997
"... I describe a new timedomain algorithm for detecting localized structures (bursts), revealing pulse shapes, and generally characterizing intensity variations. The input is raw counting data, in any of three forms: timetagged photon events (TTE), binned counts, or timetospill (TTS) data. The outpu ..."

Count Data Models in SASĀ®
, 2008
"... Poisson regression has been widely used to model count data. However, it is often criticized for its restrictive assumption of equidispersion, meaning equality between the variance and the mean. In reallife applications, count data often exhibits overdispersion and excess zeroes. While Negative b ..."

Dynamic Itemset Counting and Implication Rules for Market Basket Data
, 1997
"... We consider the problem of analyzing marketbasket data and present several important contributions. First, we present a new algorithm for finding large itemsets which uses fewer passes over the data than classic algorithms, and yet uses fewer candidate itemsets than methods based on sampling. We in ..."

Count Data Models With Selectivity
, 1996
"... This paper shows how truncated, censored, hurdle, zero in ated and underreported count models can be interpreted as models with selectivity. Until recently, such count data models have commonly imposed independence between the count generating mechanism and the selection mechanism. Such an assumptio ..."

Regression Models for Count Data in R
"... The classical Poisson, geometric and negative binomial regression models for count data belong to the family of generalized linear models and are available at the core of the statistics toolbox in the R system for statistical computing. After reviewing the conceptual and computational features of th ..."

Probabilistic Counting Algorithms for Data Base Applications
, 1985
"... This paper introduces a class of probabilistic counting lgorithms with which one can estimate the number of distinct elements in a large collection of data (typically a large file stored on disk) in a single pass using only a small additional storage (typically less than a hundred binary words) a ..."

Approximate Frequency Counts over Data Streams
 VLDB
, 2002
"... We present algorithms for computing frequency counts exceeding a userspecified threshold over data streams. Our algorithms are simple and have provably small memory footprints. Although the output is approximate, the error is guaranteed not to exceed a userspecified parameter. Our algorithms can e ..."

Essentials of Count Data Regression
, 1999
"... In many economic contexts the dependent or response variable of interest (y) is a nonnegative integer or count which we wish to explain or analyze in terms of a set of covariates (x). Unlike the classical regression model, the response variable is discrete with a distribution that places probability ..."
