The advantage of the proposed techniques is that they are not ad hoc, but are part of a common framework that can be used to test for and mitigate multicollinearity. In fields such as tourism and hospitality, where many variables are not observed directly, but measured through proxies, the ...
It is also observed that the value of L12(δ) initially decreases as δ increases; eventually, it reaches a minimum and then increases rapidly. It should be noted that this numerical method seeks the minimum value of the mean square error in the estimation of the optimal portfolio weights. ...

More commonly, MAR ties the missingness to an observed measurement, however, the missing data does not depend on the value of the missing data. In the dataset, such missingness may manifest in areas such as theCorruption Perception Indexscore not being recorded for a country that is in conflic...
Within the large dataset, all three categorizations can be observed, which accounts for some of the numerical problems encountered when applying pmm. Country conflict data often carries the complexity of missing data through multiple lenses: seeing miss- ingness through unique country-year pairs as ...
In any specific application of ridges regression, there is no guarantee that the sample estimate is a member of the class of more accurate estimates. This paper therefore reveals the importance of ridge trace to boost ridge regression estimate in the presence of multicollinearity. We observed from...
Answer to: If the error variances of a regression model are not constant, it is called: a. multicollinearity b. homoscedasticity c. nonlinearity d...
Oversampling is expected to improve the chance of minority cases being predicted from a pool of majority cases, hence improving the accuracy of the prediction model rather than returning misleading bias results, as we observed in the first experiment. A closer look at Table 13 shows that the ...
This analysis is based on the data and methodology outlined by [21], providing insights into the factors influencing Pakistan’s GDP growth. In the Figure 1, high positive relationships are observed for 𝑋2X2 with 𝑋5X5 with a coefficient of 0.75, 𝑋6X6 with a coefficient of 0.73, ...
