Command Syntax

Syntax 1 (list format)

“μ1 condition”, List(1), List(2), Freq(1) (or 1), Freq(2) (or 1), Pooled condition (On or Off)

*“Freq” can be omitted. Doing so sets “1” for “Freq”.

*“Pooled” can be omitted. Doing so sets “Off” for “Pooled”.

Syntax 2 (parameter format)

“μ1 condition”, o1 value, x1σn−1 value, n1 value, o2 value, x2σn−1 value, n2 value, Pooled condition (On or Off)

* “Pooled” can be omitted. Doing so sets “Off” for “Pooled”.
