The following is the sinusoidal regression model formula.
y = a·sin(b·x + c) + d
Tip
• Make sure that “Radian” is selected for the [Angle] setting on the Basic Format dialog box (page
14-3-2) before drawing a sinusoidal regression graph. The graph cannot be drawn correctly when
the [Angle] setting is “Degree”.
• Certain types of data may cause calculation to take a long time. This is normal and does not
indicate malfunction.
Drawing a Sinusoidal Regression Graph (
y = a·sin(b·x + c) + d)
Sinusoidal regression is best for data that repeats at a regular fixed interval over time.
u ClassPad Operation
Start the graphing operation from the Statistics application’s Graph window or List window.
From the Graph window
Tap [Calc] [Sinusoidal Reg] [OK] [OK] ".
From the List window
Tap [SetGraph][Setting...], or G.
On the Set StatGraphs dialog box that appears, configure a StatGraph setup with the
setting shown below, and then tap [Set].
Type: SinR
Tap y to draw the graph.
