OUTINTERVALS= Data Set

Each INTERVALS statement can create an output data set specified with the OUTINTERVALS= option. The OUTINTERVALS= data set contains statistical intervals and related parameters.

The number of observations in the OUTINTERVALS= data set depends on the number of variables analyzed, the number of tests specified, and the results of the tests. The OUTINTERVALS= data set is constructed as follows:

  • The OUTINTERVALS= data set contains a group of observations for each variable analyzed.

  • Each group contains one or more observations for each interval you specify with the METHODS= option. The actual number depends upon the number of combinations of the ALPHA=, K=, and P= values.

The following variables are saved in the OUTINTERVALS= data set:

Variable

Description

_ALPHA_

value of associated with the intervals

_K_

value of K= for the prediction intervals

_LOWER_

lower endpoint of interval

_METHOD_

interval index (1–6)

_P_

value of P= for the tolerance intervals

_TYPE_

type of interval (ONESIDED or TWOSIDED)

_UPPER_

upper endpoint of interval

_VAR_

variable name

If you use a BY statement, the BY variables are also saved in the OUTINTERVALS= data set.
