The data of the above eight indicators were standardized, and dimensionality was reduced using principal component analysis to calculate the enterprise growth index (IFPI), which was used for robustness testing. Meanwhile, the logProfit of net profit (logProfit) was used as a supplementary test. ...
One approach to interpreting and gaining insight into a “black box” model is to calculate the variable importance that represents the statistical significance of each variable used in relation to its effect on the resulting model. Quantifying the importance of features in a machine learning model ...
For the linear model Y=Xb+error, where the number of regressors (p) exceeds the number of observations (n), the Elastic Net (EN) was proposed, in 2005, to estimate b. The EN uses both the Lasso, proposed in 1996, and ordinary Ridge Regression (RR), propo
The non-oriented version of the SBM model is used to calculate the meta-frontier and cluster-frontiers (see Problem (6)). Generically, the overall TGRk of DMUk is then calculated as follows [78]: TGRk = ρ meta k (V RS)∗ ρ cluster k (V RS)∗ , p = 1, ..., P, (10...
In addition, spatial information was gathered to efficiently calculate various accessibility measures and locational features using geographic information technology. Quantitative spatial measures included access to transit, colleges, parks, and public amenities. Table 3 summarizes the attributes, definitions, ...
This in turn probably depends on the fact that car owners only calculate the cost of fuel and not the full cost of running a car when they reflect on the cost for a journey by car. They certainly do not consider the social cost (i.e., costs of congestion, noise, air pollution and ...
