The exception principle of management reporting suggests that, under ordinary conditions, operational staff persons make decisions, but that the same staff refer decisions to upper-level managers under exceptional conditions. Forecasts of large changes or extreme values in product or service demand are potential triggers for such reporting. Seasonality estimates in univariate forecast models an...

Data mining algorithms were used to develop models to forecast the outcome of leafroller pest monitoring decisions on ‘Hayward’ kiwifruit crops in New Zealand. Using industry spray diary and pest monitoring data gathered at an orchard block level for compliance purposes, 80 attributes (independent variables) were created in three categories from the spray diary data: (1) individual insecticide ...

This paper sorts out the current domestic carbon emission influencing factors and forecasting methods, summarizes application status of models. forecast period, difficulty modeling are reviewed. It is believed that promotion comprehensive evaluation prediction model should be promoted in future.

Purpose: The purpose of this paper is to develop a combined model composed of greyforecast model and Logistic-growth-curve model to improve the accuracy of forecast model of cargo throughput for the port. The authors also use the existing data of a current port to verify the validity of the combined model. Design/methodology/approach: A literature review is undertaken to find the appropriate fo...

I n this paper, we specify that the GARCH(1,1) model has strong forecasting volatility and its usage under the truncated standard normal distribution (TSND) is more suitable than when it is under the normal and student-t distributions. On the contrary, no comparison was tried between the forecasting performance of volatility of the daily return series using the multi-step ahead forec...

T paper investigates the capacity investment decision of a supplier who solicits private forecast information from a manufacturer. To ensure abundant supply, the manufacturer has an incentive to inflate her forecast in a costless, nonbinding, and nonverifiable type of communication known as “cheap talk.” According to standard game theory, parties do not cooperate and the only equilibrium is uni...

China Meteorological Administration (CMA) and regional centers have developed their own Numerical Weather Prediction (NWP) operation systems, which work process is complicated, including data preprocessing, analysis, model forecast, post-processing, visualization and other aspects but were lack of a unified management and monitoring. Based on the demands of NWP operation systems, this article g...

OBJECTIVES We compared the sleep of infants at risk for neuromotor delays to that of infants without such risks, and examined the predictive validity of risk indicators to the development of sleep problems. METHODS Conveniently recruited infants (n = 142) were assessed for neuromotor achievements and sleep behaviors at 4-6 months and 10-12 months of age. Assessment tools were the Harris Infan...

Prior studies evaluate the relative importance of the sources of value that financial analysts bring to the market based on the price impact of forecast revisions over the event time. We find that management earnings forecasts influence the timing and precision of analyst forecasts. More importantly, evidence suggests that prior studies’ finding of weaker (stronger) stock-price responses to for...
