On Model Selection for Autocorrelated Processes in Statistical Process Control
Using traditional control charts to monitor autocorrelated processes is not beneficial, because it will lead us to misleading detections in the processes. One of the methods used to deal with the control charts for autocorrelated process is the model‐based approach.

Packet dropping characteristics in a queue with autocorrelated arrivals
This paper provides a detailed description of the packet dropping process connected with the buffer overflows in a network node. Namely, we show the formulas for the most important loss characteristics, both in the transient and the stationary regime and

The process capability indices provide a measure of how a process fits within the specification limits. In calculating indices is usual to assume that the process data are independent.

On-line recognition of abnormal patterns in bivariate autocorrelated process using random forest [PDF]
It is not uncommon that two or more related process quality characteristics are needed to be monitored simultaneously in production process for most of time.

A Novel Scheme of Control Chart Patterns Recognition in Autocorrelated Processes
Control chart pattern recognition (CCPR) can quickly recognize anomalies in charts, making it an important tool for narrowing the search scope of abnormal causes.

Nonparametric performance hypothesis testing with the information ratio
This study proposes a nonparametric bootstrap-based test to compare performances between two portfolios in terms of their information ratio. This serves as an extension to the literature that tests performance between two portfolio investment strategies ...

Process incapability index for autocorrelated data in the presence of measurement errors
Process incapability index is a useful tool for measuring the performance of a process to maintain the quality of products. In this article, we discuss some statistical properties of the estimator of process incapability index when process observations ...

Can crude oil prices predict world tuna prices? [PDF]
World tuna prices exhibit substantial fluctuations over time. We studied monthly tuna and preceding crude oil prices from 1986 to 2018, using linear regression models with autoregressive and moving average (ARMA) errors.

Rates and Rocks: Strengths and Weaknesses of Molecular Dating Methods
I present here an in-depth, although non-exhaustive, review of two topics in molecular dating. Clock models, which describe the evolution of the rate of evolution, are considered first.
