Both the methods were executed in heteroscedastic PNN and in homoscedastic
All variables were found to be adequately homoscedastic
and linear through the examination of scatter plots, histograms, and normal Q-Q plots (Mertler & Vannatta, 2005; Tabachnick & Fidell, 2001).
Using the homoscedastic
smearing coefficient (Duan 1983), I find that weekend admission is associated with a $102 reduction in 1-year inpatient expenditures.
A visual comparison of residuals between linear and nonlinear models showed the data to be homoscedastic
and therefore the linear model was chosen because of its parsimony.
The residuals may be considered, at a visual estimate, to be homoscedastic
The error terms in this framework are assumed to be independent, homoscedastic
, and distributed multivariate Gumbel.
Log of HTX is used in the study to render the distribution nearly normal and the error term homoscedastic
When the variances between treatments (i,j) are all the same (or reasonably so), the data is considered homoscedastic
The insignificance of the dummy variable (at the 95 percent significance level) implies that the two subsamples are homogenous, and the Jarque-Bera-test and White-test indicate that the residuals are normally distributed and homoscedastic
Use of the F-test is based on the assumption of homoscedastic
The IV approach yields the same point estimators as WLS, but it produces standard errors that are consistent with the assumption that the error term in Equation (1) is homoscedastic
it] = the disturbance vector with a zero mean and a serially independent and homoscedastic
