test reg2-reg4 - not found r(111); In a varlist, reg2-reg4 means variables reg2 and reg4 and all the variables between, yet we received an error. test is confused because the - has two meanings: it means subtraction in an expression and "through" in a varlist. Similarly, '*'...
The results are summarized in Fig.2a. We found that our method provided results comparable with the PF in terms of providing an estimate for the mean of the state. We believe that minor differences in performance are because of our choice of basis functions. Clearly there is an opportunity t...
Finally, one combines those M estimation results into the desired single result. The mi command does this for you. It can be used with most of Stata's estimation commands, including with survey, survival, and panel and multilevel models. See [MI] intro. [ U ] 26 Overview of Stata ...
The standard errors from GRE can result in under-coverage, as has been reported (see Supplementary Table 4 of Hou et al.10). When the true effect size does not follow a normal distribution, we observe under-coverage for all LMM-based estimators. Nevertheless, the calibration of HEELS is ...
Conversely, tree-based methods were the only modeling techniques which did not result in the smallest (i.e., best) rank sums when combined with CDDD. Performances of SVM ensembles were mostly located below those of neural networks and tree-based techniques. In combination with MACCS, SVM ...
To get a state-of-the-art result, the network framework is becoming more and more complicated, and the loss terms are becoming more complicated, which make the training of the network difficult. Furthermore, the increase of loss terms will also pose a challenge on the selection of hyper...
Problem Until the cloud provider does install scaphandre on its hypervisors, we should enable cloud customers to estimate their power usage and thus their climate impact. Solution Integrate statistical models like https://github.com/etsy...
At the same time, however, given our relatively homogeneous sample and the missing correlations between income and car availability/PT season ticket ownership, it makes us confident that the large VTTS differences between car modes and PT are not a result of individuals’ self-selection, but ...
Unfortunately, usercmd does not allow weights. Instead, you type . expand pop . usercmd y x1 x2 to obtain your result. Moreover, there is an important principle here: the results of running any command with frequency weights should be the same as running the command on the unweighted, ...
. bootstrap r(ratio), reps(1000) seed(4567) saving(mydata): myratio bootstrapcan be used with any Stata estimator or calculation command and even with community-contributed calculation commands. We have foundbootstrapparticularly useful in obtaining estimates of the standard errors of quantile-reg...
