Difference in slope and distance between differential regression lines due to polymorphism
| Difference | t | p value | |
|---|---|---|---|
| b1 − b2 | 0.052 | 0.302 | 0.763 |
| d | 0.195 | 0.208 | 0.836 |
Given two simple linear regression lines (y1 = a1 + b1x1, y2 = a2 + b2x2), one of which is for subjects without the Arg allele and the other is for subjects with the Arg allele
b1 − b2, the difference between the two slopes, d, the distance between two regression lines in the case of the two regression lines being parallel
