In the jargon of GLS, the random-effects model fit by xtreg has exchangeable correlation within i — xtgls does not model this particular correlation structure. xtgee, however, does. [ U ] 26 Overview of Stata estimation commands 15 Alternative methods report the OLS coefficients and a version...
Moreover, the result is used to establish a sufficient condition for the OLS estimator to be inconsistent when orthogonality is suspect so that the Wu-Hausman test is not applicable. This condition is useful even when the above type of prior information is not directly available....
Estimating the numbers and whereabouts of internally displaced people (IDP) is paramount to providing targeted humanitarian assistance. In conflict settings like the ongoing Russia-Ukraine war, on-the-ground data collection is nevertheless often inadequa

For R/λ between 0.018 (R= 200 km, ν= 2 mHz) and 0.457 (R= 800 km, ν= 5 mHz), this result means that the waves propagate faster when traveling the vertical magnetic field. However, for R/λ= 0.685 (R= 1.2 Mm, ν= 5 mHz) and larger, the interpretation of ...
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 ...
A slight increase in (Mi + mi) does not result in a large increase in TEC. However, in peak hours there are more passengers in the EBs and the ratio of mi to Mi would increase. In such a condition, the improvement in MAPE would be more significant. (iv) Effects of travel ...
As a result, the number of differentially expressed genes was reduced from 1032 to 775. Using this more stringent gene signature, we re-estimated cell-type composition using DWLS. We found the results were similar to before (Supplementary Fig. 4). Furthermore, we compared the signature genes ...
If this 22 regress postestimation — Postestimation tools for regress were not a manual, having found evidence of omitted variables, we would never have run the estat hettest, estat szroeter, and estat imtest commands, at least not until we solved the omitted-variable problem. Technical note ...
