A framework fo r statistical modeling of the wideband characterABSTRACT ist ics o f the frequency-selective fad ing mul t ipa th indoor radio channel fo r geolocation applications is presented. Mul t ipath characteristics o f the channel are divided into three classes according t o availability and the strength of the direct line of sight (DLOS) path w i th respect t o the other paths. Statisti...

We describe the construction of statistical models that provide inferences about the probability that subjects will consider events to be memory landmarks. We review methods and report results of experiments probing the classification accuracy and receiver-operator characteristics of the models. Then, we discuss opportunities for integrating models of memory landmarks into computing application...

We can adapt existing techniques for the statistical modeling of music to the modeling of the quality of musical performance, resulting in a fine-grained statistical understanding of ’hardness’ in music performance. This drives AI-assisted applications for improving skill. We present modeling results using various probabilistic models to model performance in the simplified setting of rhythm games.

Smooth curves a.re often used to illustrate the relationship between two variables. They are also an important building block in many recent statistical models. A procedure to estimate such a curve is called a smoother. This paper discusses currently available smoothers and introduces the class of maximum likelihood smoothers. A variety of other statistical techniques are shown to be applicable...

This paper presents an analysis of a rules-based approach and a statistical anomaly approach to Intrusion Detection Systems (IDS). Two IDS systems are implemented. Analysis and comparisons of the systems are presented, as well as conclusions regarding the two approaches.

This article presents a conceptual framework for clarifying the network hypotheses embedded in policy theories and how they relate to macrolevel political institutions and microlevel political behavior. We then describe the role of statistical models of networks for testing these hypotheses, including the problem of operationalizing theoretical concepts with the parameters of statistical models...

This paper analyzes the conceptual framework of three statistical methods, multiple regression, path analysis, and structural equation models. When establishing research model of the statistical modeling of complex social phenomenon, it is important to know the strengths and limitations of three statistical models. This study explored the character, strength, and limitation of each modeling and...

An important role of statistical analysis in science is for interpreting and communicating statistical evidente per se showing “what the data say.” Although standard methods (hypothesis testing, estimation, confidence intervals) are routinely used for this purpose, the theory behind those methods contains no defined concept of evidente, and no answer to the basic question, “When is it correct t...

For second-hand products sold with warranty, the expected warranty cost for an item to the manufacturer, depends on (i) the age and/or usage as well as the maintenance history for the item and (ii) the terms of the warranty policy. The paper develops probabilistic models to compute the expected warranty cost to the manufacturer when the items are sold with free replacement or pro rata warrantie...
