Effect of Air Quality of Operating Rooms on Infections, 8 Operating Rooms, Traditional Versus Regularized Regressions

Traditional and regularized regressions were used to assess the effect of air quality of operating rooms on infections. Particularly the factors humidity, filter capacity and air volume change are supposed to be important determinants. The best result was obtained by the Ridge and Elastic Net data. The worst by the standardized Traditional data. The unstandardized Traditional regression produced two significant p-values (0.025 and < 0.001), while the standardized Traditional regression produced only one reasonable and null strong correlation.
