Fig.1. Plot of residual ri versus fitted value y^i : (a) model appears to be correct; (b) increasing variance; (c) model is inadequate. 2. Outliers: A few of ti may be much larger in absolute magnitude than all the others. Any observation that looks out of place is generally refe...
Time series effects are frequently detected by lag plots of the residuals, i.e., plots of eˆi versus eˆi−k for various k. Besides the plot of residuals versus fitted values, histograms and q–q plots are helpful in assessing distributional properties of the errors. Show moreView ...
The residual plot below clearly has a pattern! If you know the fitted value, you can use it to predict the residual. For instance, fitted values near 5 and 10 tend to have positive residuals while fitted values near 7 tend to have negative values. If they were truly random, you wouldn...
In multiple regression, the residual plot of the residuals versus predicted values can be used to [{Blank}]. (Choose all that apply.) a. determine if there are outliers b. check the condition that the residuals have constant variation c. check the conditiExplain the differ...
Answer to: Suppose your R-squared is 0.455, and the explained (or model) sum of squares (ESS) is 2150. What is the residual (or unexplained) sum of...
. MRD-tests done during/after consolidation chemotherapy had higher ORs compared with MRD-tests during/after remission induction (12.8 [5.8, 28.6] versus 1.6 [1.0, 2.6]). Finally, MRD-tests done posttransplant had higher ORs compared with tests done pretransplant (21.0 [6.8, 65.3] versus 6.3...
According to our experience, ddPCR is practical, is cost and time saving, and allows for an immediate and easy data interpretation. The possibility of performing the method both at diagnosis and follow-up in one single reaction, by simply modulating the amount of the input material, makes this...
The results demonstrate that our method is lightweight and practical, qualifying it for continuous monitoring applications in clinical settings for automated ECG interpretation to support cardiologists.

The data distribution pattern was identified using the normal % probability versus the studentized residual plot. As shown in Figure 5, the internally studentized residuals were roughly plotted along the diagonal line, indicating that the model response had a normal distribution. Thus, the models ...
(a) Residual stress versus spindle; (b) Residual stress versus feed; (c) Residual stress versus spindle rotate. In Figure 7a, the feed speed and spindle rotation angle are constant, 35 mm/min and 45°, respectively. It can be found that the depth of the residual stress layer varies ...
