Linear Estimation and Correlation Coefficient

When you execute the j or ª function, the linear estimate (ŷ or
placed in the X-register, and the correlation coefficient (r) is placed in the Y-
register.
Linear Estimation. With statistics accumulated in registers R
predicted value for y (denoted ŷ) can be calculated by keying in a known value
for x and pressing ´j. Similarly, a predicted value for x (denoted
be calculated by keying in a known value for y and pressing ´ª.
