| The RELIABILITY Procedure |
FMODE Statement
- FMODE keyword=
variable ('value1' ... 'valuen');
Use
the FMODE statement with data that have failures attributable
to multiple causes, or failure modes.
You can analyze data by either keeping or eliminating specific
failure modes with the FMODE statement. Use this statement
in conjunction with the ANALYZE, MODEL,
PROBPLOT, or RELATIONPLOT
statements. An FMODE statement placed anywhere after the PROC RELIABILITY
statement and before the RUN statement affects analyses
performed by all ANALYZE, MODEL,
PROBPLOT, and RELATIONPLOT
statements.
If you specify the keyword KEEP, the life distribution
for only the identified failure modes is estimated, with all other
failure modes treated as right-censored data.
If you specify the keyword ELIMINATE,
the life distribution that results if
the failure modes identified are completely eliminated is estimated.
The keyword ELIMINATE causes the failure modes identified to
be treated as right-censored data and causes a single life distribution
to be estimated for the remaining data.
The failure mode for an observation in the input data set
is identified by the value of variable,
where variable is any numeric or character variable in the
input data set. You specify failure modes to keep or eliminate
by listing variable-values
('value1' ... 'valuen')
in parentheses after the
failure mode variable name. The list of variable-values
must have each entry enclosed in single quotes, with entries
separated by blanks or commas.
