Logistic regression is best for data whose values continually increase over time, until a saturation point is reached.
uClassPad Operation
Start the graphing operation from the Statistics application’s Graph window or List window.
From the Graph window
Tap [Calc] [Logistic Reg] [OK] [OK] ".
From the List window
