The following shows the meaning of each item in the case of list data specification.
β & ρ ............................ p-value test conditions ("G 0" specifies two-tail test, "< 0"
XList ............................ list for
YList ............................ list for
Freq ............................. frequency (1 or List 1 to 20)
Save Res ..................... list for storage of calculation results (None or List 1 to 20)
Execute ....................... executes a calculation
After setting all the parameters, align the cursor with [Execute] and then press the function key
shown below to perform the calculation.
