[HP-12C] Angular coefficent from linear regression off by 1
While doing linear regression on the 12C, I noticed the last digit of the angular coefficient is usually off by 1. Does anyone know why? I thought the 12C used the same algorithm as the 15C.

Example:
Code:

x       y
0.00    1.0
0.15    2.1
0.45    3.9
0.83    8.1
1.12    14

The 15C will return y=0.159340862+11.09933164. The 12C gives ...165 instead.

Thank you.
