RISK AND RETURNS OF DIVERSIFIED CROPPING SYSTEMS UNDER NONNORMAL, CROSS-, AND AUTOCORRELATED COMMODITY PRICE STRUCTURES [PDF]
This study analyzes the risks of diversified tropical cropping systems that combine cocoa, plantain, and tree-crop components in different proportions versus traditional monocultures.

Monitoring the Process Mean of Autocorrelated Data [PDF]
, 2008 When modeling the stochastic behavior of a sequence { } t X of the quality measurement X on the output of a production process, it is usually assumed the measurements taken over time are independent and identically distributed.

Autocorrelated multivariate process control: a geometric brownian motion approach
, 2013 In real life we always come across autocorrelated multivariate process where the present process is related to the previous process. This type of process can be modeled using the traditional multivariate time series models and then the process control ...

Conservation Science and Practice, EarlyView.To understand the range‐wide drivers of Arizona Toad distribution and anticipate future changes, we combined 13 datasets covering distinct portions of the range in an integrated species distribution model. We estimate that the current occupied range is 1/4–1/3 of previously defined range boundaries and that increasingly dry conditions will lead to ...

Monitoring of the BTA Deep Hole Drilling Process Using Residual Control Charts [PDF]
Deep hole drilling methods are used for producing holes with a high lengthto- diameter ratio, good surface finish and straightness. The process is subject to dynamic disturbances usually classified as either chatter vibration or spiralling. In this work,

Quality control of DEMs using check surfaces
Annals of GISThis paper proposes the use of check surfaces or ‘patches’ for the assessment of Digital Elevation Model (DEM) elevations and derived variables (e.g. slope and aspect).

Estimating the Parameters of Degradation Models when Error Terms are Autocorrelated
Austrian Journal of Statistics, 2016 The need of autocorrelation models for degradation data comes from the facts that the degradation measurements are often correlated, since such measurements are taken over time.

Speculation in the United Kingdom, 1785‒2019
The Economic History Review, EarlyView.Abstract Speculation has long been thought to have significant economic effects, but it is difficult to measure, making it challenging to examine these effects empirically. In this paper we measure speculation in the United Kingdom since 1785 by using business and financial reporting in The Times newspaper.

Fisheries Oceanography, EarlyView.ABSTRACT The linkage between growth rate and feeding success in fish larvae has received much attention as a potential indicator of future growth and survival potential. Given the increasing evidence that the growth–survival relationship is highly variable, the growth–feeding linkage would also exhibit variable dynamics among cohorts of the same ...
