NPAR TESTS
performs nonparametric tests.
Non parametric tests make very few assumptions about the distribution of the
data.
One or more tests may be specified by using the corresponding subcommand.
If the /STATISTICS
subcommand is also specified, then summary statistics are
produces for each variable that is the subject of any test.
Certain tests may take a long time to execute, if an exact figure is required.
Therefore, by default asymptotic approximations are used unless the
subcommand /METHOD=EXACT
is specified.
Exact tests give more accurate results, but may take an unacceptably long
time to perform. If the TIMER
keyword is used, it sets a maximum time,
after which the test is abandoned, and a warning message printed.
The time, in minutes, should be specified in parentheses after the TIMER
keyword.
If the TIMER
keyword is given without this figure, then a default value of 5 minutes
is used.
