Distribution Functions
DISTR menu
Note: Selection of any of the DISTR functions will take the user to a wizard screen for that function
when the STAT WIZARDS is set to ON in Mode. Color spinner menu to set the graph color is available.
To display the DISTR menu, press y =.
Note: Use Catalog Help for more syntax help when needed.Select a menu item and then press à to go
to a syntax help editor (if the menu item is supported).
L1â99 and 1â99 specify infinity. If you want to view the area left of
upperbound, for example, specify
lowerbound= L1â99.
