WebLinear regression analysis showed that the earlier onset time of mild hypothermia, the lower incidence of MODS ( R 2 = 0.915, P = 0.013). Conclusion The application of mild hypothermia in 2 hours can effectively protect the physiological function of EHS organs and reduce the incidence of MODS. WebThe linear regression analysis results show that the R 2 of the daytime model is 0.92, which has high consistency; the average R 2 at night is 0.38; the averages R 2 before and after rainfall are 0.50 and 0.83, respectively; and the average RMSE is 1.94 °C.

If the R2 is between 0 and 1, the model allows you to partially predict exam scores. The model’s estimates are not perfect, but they’re better than simply using the average exam score. If the R2 is 1, the model allows you to perfectly predict anyone’s exam score. More technically, R2 is a measure of goodness of fit. See more The coefficient of determination (R²) measures how well a statistical model predicts an outcome. The outcome is represented by the model’s dependent variable.
