Inference for regression
An HP Prime calculator can perform tests and calculate
intervals based on inference for linear regression. These
calculations are based on the t-distribution.
Hint: If you have been using the Statistics 2Var app to
explore a linear regression and you want to use the same
data for this procedure, you will have to import it
manually. For example, suppose your x-values are in list
C1 of the Statistics 2Var app and your y-values are in list
C2.
