Scaled residuals图
WebAdequate model fit was judged by four criteria: goodness-of-fit statistics (p-value >0.1), scaled residuals (within ±2 units) at the data points (except the control) closest to the predefined BMR, BMCL values that are not 10 times lower than the lowest non-zero dose, and visual inspection of the proximity of the predicted dose-response curve ... WebDec 22, 2024 · A residual is the difference between an observed value and a predicted value in a regression model. It is calculated as: Residual = Observed value – Predicted value If we plot the observed values and overlay the fitted regression line, the residuals for each observation would be the vertical distance between the observation and the regression line:
