[HP12C] 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:
The 15C will return y=0.159340862+11.09933164. The 12C gives ...165 instead. Thank you.
