Selecting option 3 of the CODA Summary Statistics Defaults Menu produces the following prompt:
Enter quantiles required, separated by commas (Default = 0.025, 0.25, 0.5, 0.75, 0.975): 1:
The user should then type the value of each quantile required as a fraction between 0 and 1. Once all values have been entered, press the <RETURN> key twice to return to the CODA Summary Statistics Defaults Menu.
