Manipulating the components of an n25
Although an n25 statement does not print any rows in the table, it does create three rows which are used as part of statistical calculations such as means and standard deviations. These rows are:
The sum of x2.
The sum of x.
The sum of n.
For an explanation of these values in Quantum terms and further information about n25 statements, see n25 statements.
To refer to any of these figures on an m statement you must either give the n25 an identifier or refer to it by its absolute position in the axis. The individual elements of the n25 can then be called up as:
#pos.1 or id.1 for the sum of x2.
#pos.2 or id.2 for the sum of x.
#pos.3 or id.3 for the sum of n.
where pos is the absolute position of the n25 in the axis, and id is an identifier assigned to the n25 with id=.
