model: Adata.framecontaining the dependent and explanatory variables as well as individual and time indices (if provided). coefficients: A list holding (i) aT×p(1)×K^array of the post-Lasso group-specific functional coefficients and (ii) aK×p(2)matrix of time-constant parameter estimates ...
The paper gives conditions under which, with probability approaching 1 as the sample size increases, penalized maximum likelihood (PML) estimation with the adaptive LASSO (AL) penalty distinguishes correctly between zero and non-zero parameters. The paper also gives conditions under which PML reduces ...
Poverty Modeling in North Sumatera Province Considering County Location Using Geographical Weighted Regression and LASSO Spatial data is data that contains the influence of location with non-homogeneous variance at each location, or spatial heterogeneity. To address spatial h... O Darnius,YGC Turnip,Sut...
Numerical and theoretical models of tropical cyclones indicate that the maximum wind speed in mature storms is sensitive to the ratio of the enthalpy and momentum surface exchange coefficients and that the spinup time of tropical cyclones varies inversely with the magnitude of these coefficients. At ...
First 1.repair had to be removed from the model because it would have an infinite coefficient. Then, the 10 observations that led to the problem had to be eliminated, as well, so as not to bias the remaining coefficients in the model. The 10 observations that are not used are the 10 ...
