| Dec 29, 2015 at 11:29 | comment | added | Nick Cox | The easy way into this is to note that as residual $=$ observed $-$ fitted, particular observed values (0, 1, ....) define lines with negative unit slope and differing intercept. Your log scale for fitted warps them into curves. | |
| Dec 29, 2015 at 5:10 | comment | added | Glen_b | Here's one. A similar issue can be seen in multiple regression if you have a discrete response. | |
| Dec 29, 2015 at 3:49 | comment | added | Glen_b | The fact that you have count data in your response is what causes that. The leftmost "stripe" in the bottom plot will almost certainly be the 0's, the next one the 1's, and so on. This is addressed in several questions on site. I'll try and find you some. | |
