On the basis of the output of autoplot() (assuming that the linearity assumption and constant variance assumption are satisfied) does there seem to be any issues with the normality assumption.单项选择题

A

No, the residual vs. leverage plot is close to flat indicating that there are no issues with the normality assumption.

B

Yes, by looking at the scale-location plot, we see a systematic deviation of the residuals from a flat line, indicating a failure of the normality assumption.

C

No, there is an increasing trend in the scale-location plot indicating that there are no issues with the normality assumption.

D

Yes, by looking at the QQ-plot we see a systematic deviation from the dashed line, indicating a failure of the normality assumption.

It is extremely flexible when wet, and is adapted to create interesting shapes. Many urban public buildings, such as universities, have also used concrete as the main material to indicate strength and permanence. Instead of keeping Brutalist buildings, many are being demolished to make space for modern styles. However, this does not acknowledge the cultural history of these buildings, and is not sustainable.
