We specify a Bayesian, Pillow geoadditive Stochastic Frontier Analysis (SFA) model to assess hospital performance along the dimensions of resources and quality of stroke care in German hospitals.With 1,100 annual observations and data from 2006 to 2013 and risk-adjusted patient volume as output, we introduce a production function that captures qual
Leaf area controls on energy partitioning of a temperate mountain grassland
Using a six year data set of eddy covariance flux measurements of sensible and latent heat, soil heat flux, net radiation, above-ground phytomass and meteorological driving forces energy partitioning was investigated at a temperate mountain grassland managed as a hay meadow in the Stubai Valley (Austria).The main findings of the study were: (i) Ene
ON NONRESPONSE CAUSALITY TESTING IN ROTATING PANEL DESIGNS UNDER THE COX MODEL
High survey nonresponse in unemployment duration studies may have a strong effect Ashley Wilde on inference if exit from unemployment affects the chance of nonresponse (nonresponse causality).In rotational studies large part of the nonresponse results from panel attritions.A method to test the presence of the causality mechanism for rotating panel
