u u u u u Regression Formula Copy Function from a Regression Calculation Result
Screen
In addition to the existing regression formula copy function that lets you copy the regression
calculation result screen after drawing a statistical graph (such as Scatter Plot), STAT2 also
adds a function that lets you copy the regression formula obtained as the result of a regression
calculation. This type of copy operation is performed by pressing 6(COPY).
k k k k k Tests, Confidence Interval, and Distribution Calculations
STAT2 adds functions for performing tests, confidence interval, and distribution calculations.
This manual fully describes each of these calculations in separate chapters: Chapter 2 Tests,
Chapter 3 Confidence Interval, and Chapter 4 Distribution.
u u u u u Parameter Settings
The following describes the two methods you can use to make parameter settings for test,
confidence interval, and distribution calculations.
• Selection
With this method, you press the function key that corresponds to the setting you want to
select from the function menu.
• Value Input
With this method, you directly input the parameter value you want to input. In this case,
nothing appears in the function menu.
· Pressing i returns to the list input screen, with the cursor in the same position it was at
before you started the parameter setting procedure.
· Pressing ! i (QUIT) returns to the top of list input screen.
· Pressing w without pressing 1 (CALC) under "Execute" item advances to calculation ex-
ecution. To return to the parameter setting screen, press i, A, or w.
u u u u u Common Functions
• The symbol " ! " appears in the upper right corner of the screen while execution of a calcula-
tion is being performed and while a graph is being drawn. Pressing A during this time
terminates the ongoing calculation or draw operation (AC Break).
• Pressing i or w while a calculation result or graph is on the display returns to the param-
eter setting screen. Pressing ! i (QUIT) returns to the top of list input screen.
