An Indirect Solution to WPLTS Group Decision Making Problem
To study the problem of weighted probabilistic linguistic term set (WPLTS) multi-attribute group decision making. Firstly, WPLTS and WPHFS are defined, and a method to convert WPLTS to WPHFS is given. Secondly...

Global Optimization for the Concave-Concave Multiplicative Programming with Coefficient
In this paper, we present a global optimization algorithm for globally solving the problem (CMPC) of minimizing a concave-concave multiplicative function with coefficient over a compact convex set. We firstly ...

Linear Programming Subject to Max-Product Fuzzy Relation Inequalities with Discrete Variables
In this paper, we introduced the linear programming subject to max-product fuzzy relation inequalities with discrete variables to denote the optimization management model of physical distribution. It is shown ...

Analysis and Interpretation of Sedentary Behaviour Data
Never before, perhaps due to widely available wearable devices and the ubiquity of mobile phones, has it been so easy and convenient to collect physical activity and sedentary behaviour data. Yet, the availabl...

Improved Convergence Rates of Normal Extremes
It is well known that the convergence of the normal extremes to the limiting Gumbel distribution is extremely slow, at the rate of ...

Applications of Multivariate Quasi-Random Sampling with Neural Networks
Generative moment matching networks (GMMNs) are suggested for modeling the cross-sectional dependence between stochastic processes. The stochastic processes considered are geometric Brownian motions and ARMA–G...

Chapter
Model-Based Inverse Regression and Its Applications
One fundamental concept in regression is dimension reduction, the basic idea being to reduce the dimension of the predictor space without loss of information on the regression. To avoid the curse of dimensiona...

Modeling Species Specific Gene Expression Across Multiple Regions in the Brain
Motivation: The question of what makes the human brain functionally different from that of other closely related primates, such as the chimpanzee, has both philosophical as well as practical implications. One of ...

Cosine Similarity-Based Classifiers for Functional Data
In many situations, functional observations in a class are also similar in shape. A variety of functional dissimilarity measures have been widely used in many pattern recognition applications. However, they do...

A Simulation Study Comparing SNP Based Prediction Models of Drug Response
Lack of replication on findings and missing heritability are two of the major challenges in Pharmacogenetics (PGx) studies. Recently developed statistical methods for genome-wide association studies offer grea...

Identifying and Comparing Writing Process Patterns Using Keystroke Logs
There is a growing literature on the use of process data in digitally delivered assessments. In this study, we analyzed students’ essay writing processes using keystroke logs. Using four basic writing performa...

A Novel Framework for Bayesian Response-Adaptive Randomization
The development of response-adaptive randomization (RAR) has taken many different paths over the past few decades. Some RAR schemes optimize certain criteria, but may be complicated and often rely on asymptoti...

Exact Likelihood-Based Point and Interval Estimation for Lifetime Characteristics of Laplace Distribution Based on hybrid Type-I and Type-II Censored Data
In this chapter, we first derive explicit expressions for the Maximum likelihood estimators (MLEs) of the parameters of Laplace distribution-based on a hybrid Type-I censored sample (Type-I HCS). We then deriv...

Investigating an Intervention’s Causal Story: Mediation Analysis Using a Factorial Experiment and Multiple Mediators
Behavioral, biobehavioral, and biomedical interventions presume a causal story. This causal story is used to create a conceptual model of why the intervention caused the observed outcome. Methods are needed to in...

Market Based Credit Rating and Its Applications
Credit rating plays a critical role in financial risk management. It is like a name tag of a firm indicating its health condition. Generally, ratings involve a lot of firm-specific information which is hard to...

Two-sample tests for multivariate functional data
We consider two–sample tests for functional data with observations which may be uni– or multi–dimensional. The new methods are formulated as L2–type criteria based on empirical characteristic functions and are...
