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 ...
The outcome is a result of two processes. First a probit process describes the presence of excess zeros, which is a negative outcome. Second, an ordered probit process, conditional on a positive outcome from the probit process, describes the ordered outcome. [ U ] 26 Overview of Stata ...
Although they have limited application for signal extraction, these smoothers have all been found to be optimal for some underlying modern time-series models; see [TS] tssmooth. Diagnostic tools Stata's time-series commands also include several preestimation and postestimation diagnostic and ...
However, the research result about these fusion filters based on CFF is not found. Consequently, to meet accuracy requirements, the centralized filter will be designed; To consider real time, parallel filter will be designed; To meet the needs of network packet loss and delay, sequential filter...
Reference source not found.. Unlike the horizontal attitudes, the heading estimation is affected by the DOV indirectly. Furthermore, as is well recognized, the observability of the heading is much weaker than that of the horizontal attitudes, so the navigation Kalman filter may need Sensors 2019,...
In the above PLS regression results, individual wavelength contributions by MC, pH, and SSC contents in tomatoes was not considered in the prediction results. This was because the PLS regression method first applied linear transform to the entire individual wavelength data [34]. As a result, it...
Result and Discussion A great deal of research has been conducted on methods of estimating depth, but not much research has been conducted to compare methods by applying them to actual envi- ronments, especially underground utility tunnels. Therefore, we compared two methods of estimating depth ...
This regulation could result in a deviation of rs from the estimation by Equations (6) and (7), and consequently the poor efficiency of both the PM-KP approach and the PM-FAO approach in the case of the dry air. In the future, the Asian summer monsoon is predicted to be extended and...
As a result, the derived qe satisfies Equation (20), which means the orientation represented by qe is relative to qB: qe = qA ⊗ qB∗ (19) qA = qe ⊗ qB (20) qe is also a quaternion which is not intuitive. Converting qe to Euler angles makes it easy to be understood and ...
This familiarity could be a result of the shape of the countries and regions that are considered not distorted. Second, the Robinson projection is still widespread in Belgium, as well as in the US [57], since it was selected as the primary map projection by the National Geographic Society ...
