Regression analysis on data in Table 2 resulted in the following estimated long-term expansion cost function (million Jordanian dinars (mjd) per mcm): with R2 = 0 0.9967. Because b exceeds 1, marginal and average costs are increasing. (The standard error of the slope coefficient is 0.028;...
In contrast, rich countries are distributed around the optimum of this function. A linear regression translates this relation into (inconclusive) statements that the rich countries are not vulnerable at all, or depending on the exact specification, might be affected slightly in a positive or ...
Footnote 11 We use a slightly simplified HARA utility function (see Appendix II): $$U\left(H\right)=\left[\frac{1-\gamma }{\gamma }\right]{Z}^{\gamma },$$ (13) where \(Z=H+\eta\). The parameter \(\eta\) has the same units of measurement as \(H\), and can be ...
A preference-based scoring function can be used to convert the descriptive information to a summary index score (utility weight). More than 15 value sets are available for scoring the EQ-5D, based on rating scale and time trade-off (TTO) valuation derived from general population surveys in ...
The real-time calibration function would vary with the specific location. As a basis for the spatial calibration model, the function was assumed to be related to locations, and the coefficient estimation was carried out in spatial regression. Moreover, regional PM2.5 concentration estimations were ...
Therefore, the cost function specification of the OLS regression model may be written as: Equation 3 WhereUCiis the natural log (ln) of cost per bed-day in 1998 I $ in theithhospital;X1is ln of GDP per capita in 1998 I $;X2is ln of occupancy rate;X3,4are dummy variables indicating...
In this section, we propose a Discriminative Cost Sensitive Laplacian Score (DCSLS) for face recognition. Firstly, we introduce the model of DCSLS, and then analysis its connection with other classical methods, at last provide the mathematical derivation. Experiments In this section, ORL [2], ...
The derivation of the optimal consumption under a CC tariff is more complex because the cost function is concave here. In general, there will thus exist an optimal consumption level for each tariff segment (i.e., before and after reaching the cost cap) of the CC tariff. Therefore, it is...
Whilst this might not be justified, and indeed was addressed in Wardman (1994), the formulation of the GJT function is not the focus of this paper. Finally, what might be regarded as the conventional economics approach would be to enter into the demand model separately each of the key ...
