4、If a destination was not found, the action sets an error message and rejects the request.如果目的地未找到，则该操作将设置一个错误消息并拒绝该请求。5、If the method is not found in any parent, an error-trapping method is invoked.如果在任何父对象中都没找到该方法，会调用一个...
Hi All, Stata issues an error message saying "last estimation results not found, nothing to store" when I try to store estimation results from an estimation command I wrote. However, when I type -ereturn list-, all the saved scalars, matrices, macros and so on show up. Stephens Jenkins ...
Environmental stress due to climate or pathogens is a major threat to modern agriculture. Plant genetic resistance to these stresses is one way to develop more resilient crops, but accurately quantifying plant phenotypic responses can be challenging. Her
Traditionally, forest aboveground biomass (AGB) is estimated with allometric growth equation by measuring tree height and diameter at breast height in field survey, which could provide the accurate result at plot scale [28,52]. This approach is time-consuming and laborious and impossible to map AG...
feature selection, classifier type selection and classifier parameter tuning takes place on the data not left out during each CV loop. It has been shown that violating this principle in some ways can result in very biased estimates of the true error. One way is to use all of the training ...
A complex domain structure was found in this solid solution. Most importantly, the high piezoelectric properties obtained in the MPB composition was determined to arise from the significantly enhanced intrinsic contribution as evidenced by ... Z Liu,Y Yuan,Z Luo,... - 《Journal of Materials Chem...
An unexpected result is an increase in the upward flexibility in no-price schemes if the time-interval is reduced (for example, from 1-hour to 30-minutes), while in real-time pricing, the flexibility decreases, as seen in Table 3. The expected result was a flexibility increase if the tim...
Therefore, we ran random searches for a single L2/3 PC and L4 LBC clone and found that the best hyperparameters from the first search with the L5 PCs were not outperformed by any new hyperparameter sets tested. After exploring the hyperparameter space, we found the best performing CNN ...
At present, the procurement speed does not guarantee that all farmers in the region can be visited on time. This can result in crop value deteriorations—mainly fungal contamination [46,47,48,49]. We also argue that substituting the manual procurement method with suitable technology could, in ...
In fact, the random-walk model can be treated as a first order autoregressive process that has a root on the unit circle, which does not satisfy the stationarity condition [28]. As a result, the oscillations and the biased error appearing in the estimated input time history can be reduced...
