Let's say I've ran a linear regression and I'm checking the model diagnostics. I made a histogram of the residuals and they appear more or less normally distributed as below.
I thought for a long time that normally distributed residuals like below also indicated that the residuals are homeskedastic. However, I am I right in saying that heteroeskedastic residuals like below would also be normally distributed? Or in other words, we cannot tell if residuals are homeskedastic or heteroeskedastic just by plotting a histogram?
