Asymptotic simultaneous confidence intervals for the probabilities of a multinomial distribution
… confidence intervals for the probabilities of a multinomial distribution. The approach used is to consider the Chi-square goodness of fit statistic as a function of the population parameters and to invert this function to obtain a set of simultaneous confidence intervals for the parameters The …

Linear and log-linear models based on generalized inverse sampling scheme
… count data. Also negative binomial and negative multinomial (NMn) models are applicable when there is only one rare category in the population. Here, a new model, based on generalized inverse sampling scheme, is introduced to study several rare events simultaneouly. The generalized inverse …

Skill Evaluation in Women's Volleyball
… Data in the count matrix were assumed to have a multinomial distribution. A Dirichlet prior was formulated for each row of the count matrix, so posterior estimates of the transition probabilities were then available using Gibbs sampling. The different paths in the transition probability matrix …

The moments and distribution for an estimate of the Shannon information measure and its application to ecology
… deals primarily with the moments and distribution H̅ = - Σ n<sub>i</sub>/N logn<sub>i</sub>/N. Some techniques of obtaining multivariate moments, in particular multinomial moments, are given. I The approach used In obtaining the moments of H̅ was through the probability generating …

Statistical Methods For Resolving Intratumor Heterogeneity With Single-Cell Dna Sequencing
… software for calculating probabilities from a multinomial distribution was written to estimate the number of cells that must be sequenced (chapter 2). Two new methods were developed for predicting the number of mutations which would be discovered in additional single-cell sequencing of a tumor …

On Learning and Covering Structured Distributions
… related to learning and covering structured distributions: Hypothesis Selection: We provide an improved and generalized algorithm for selecting a good candidate distribution from among competing hypotheses. Namely, given a collection of ... hypotheses containing at least one candidate that is …

The Advancements on the Interface of Statistical Computing, Survival Analysis, and Degradation Analysis
… the probability mass function (pmf) of a Poisson multinomial distribution (PMD). However, efficient methods for computing the pmf of the PMD have yet to be developed. To bridge this gap, this dissertation introduces three distinct methods to calculate the pmf of the PMD under different …

Corruption and Policy Capacity
… a regularised variational autoeconder and a multinomial distribution to generate alternative procurement networks. The model is able to produce interpretable results that assist on the analysis of these large networks.

The Accuracy of River Bed Sediment Samples
… health is the streambed's sediment size distribution. This distribution affects streambed stability, sediment transport rates, and flood levels by defining the roughness of the stream channel. Adverse effects on water quality and wildlife can be expected when excessive fine sediments …

Bayesian Methods to Characterize Uncertainty in Predictive Modeling of the Effect of Urbanization on Aquatic Ecosystems
… with available data using conjugate Dirichlet-multinomial distribution forms. The resulting models elucidate differences between regional responses to urbanization (particularly due to background agriculture and precipitation) and address the influences of multiple urban induced stressors …

Cumulative Sum Control Charts for Censored Reliability Data
… professionals use a number of non-normal distributions to model the resulting lifetime data with the Weibull distribution being the most frequently used. If one is interested in monitoring the quality and reliability characteristics of such processes, one needs to account for the …

A user-centred approach to information retrieval
… approach to represent each social position as a multinomial distribution over words. This approach estimates a topic from a document collection for each position. To construct such a collection for a particular position, I propose a seeding algorithm that extracts a set of terms relevant to the …

Analysis of Discrete Data under Order Restrictions
… concepts are extended to deal with independent multinomial populations. Natural orderings such as stochastic ordering and cumulative ratio probability ordering are discussed. Methods are developed for the estimation and testing of differences between binomial as well as multinomial populations …
