Selecting the Number of Replications in a Simulation Study.
Dmaz-Emparanza, Ignacio - EconWPA - 1996
accuracy with which the distribution is calculated will rely on this number of replications. In this work, a relationship … between the number of replications and the accuracy of the estimate is obtained, so that if it is wanted to get a prefixed … value for the accuracy it is possible to determine which will be the minimum number of replications necessary for it. …

The Data Quality Concept of Accuracy in the Context of Public Use Data Sets
Kuchler, Carsten; Spiess, Martin - 2006
Like other data quality dimensions, the concept of accuracy is often adopted to characterise a particular data set … means of a single survey at hand. This ambiguity can be resolved by assigning ?accuracy? to survey processes that are known … setting up a data set and argue that the so called ?hit-rate? criterion, that is intended to measure the accuracy of a data …

Golden Rule of Forecasting: Be conservative
Armstrong, J. Scott; Green, Kesten C.; Graefe, Andreas - Volkswirtschaftliche Fakultät, … - 2014
This paper proposes a unifying theory of forecasting in the form of a Golden Rule of Forecasting. The Golden Rule is to be conservative. A conservative forecast is consistent with cumulative knowledge about the present and the past. To be conservative, forecasters must seek all knowledge...

Estimating standard errors for the Parks model: Can jackknifing help?
Reed, W. Robert; Webb, Rachel S. - 2010
Non-spherical errors, namely heteroscedasticity, serial correlation and cross-sectional correlation are commonly present within panel data sets. These can cause significant problems for econometric analyses. The FGLS(Parks) estimator has been demonstrated to produce considerable efficiency gains...
