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...

Sensitivity of propensity score methods to the specifications
Zhao, Zhong - 2005
Propensity score matching estimators have two advantages. One is that they overcome the curse of dimensionality of covariate matching, and the other is that they are nonparametric. However, the propensity score is usually unknown and needs to be estimated. If we estimate it nonparametrically, we...

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...
