When there is a list specified for the [Resid List] item on the Setup screen, regression formula residual data is automatically saved to the specified list after the calculation is finished.

•You cannot draw a graph for LinearReg t Test.

•[Save Res] does not save the Β & Ρ conditions in line 2.

•When the list specified by [Save Res] is the same list specified by the [Resid List] item on the Setup screen, only [Resid List] data is saved in the list.

• Ƶ2 Test Common Functions

You can use the following graph analysis functions after drawing a graph.

• (CHI) ... Displays Χ2 value.

Pressing (CHI) displays the Χ2 value at the bottom of the display, and displays the pointer at the corresponding location in the graph (unless the location is off the graph screen).

• (P) ... Displays p-value.

Pressing (P) displays the p-value at the bottom of the display without displaying the pointer.

•Executing an analysis function automatically stores the Χ2 and p values in alpha variables C and P, respectively.

•Ƶ2 GOF Test (Ƶ2 one-way Test)

The Χ2 GOF Test (Ƶ2 one-way test) tests whether the frequency of sample data fits a certain distribution. For example, it can be used to determine conformance with normal distribution or binomial distribution.

Perform the following key operations from the statistical data list.

(TEST)

(CHI)

(GOF)

Next, specify the lists that contain the data. The following shows the meaning of the above items.

Observed ......	name of List (1 to 26) that contains observed counts (all cells positive
	integers)
Expected.......	name of List (1 to 26) that is for saving expected frequency
CNTRB .........	Specifies a list (List 1 to List 26) as the storage location of the contribution
	of each observed count obtained as calculation results.
