SSPAN Statement
- SSPAN options ;
The SSPAN statement applies sliding spans analysis
to determine the suitability of seasonal adjustment
for an economic series.
The following options can appear in the SSPAN Statement:
- NDEC= n
-
specifies the number of decimal places shown on selected
Sliding Span reports. This option has no effect
on the precision of the variables values in the OUTSPAN
output data set.
- CUTOFF= value
-
gives the percentage value for determining an
excessive difference within a span for the seasonal factors,
the seasonally adjusted series, and month-to-month and
year-to-years differences in the seasonally adjusted series.
The default value is 3.0. The use of the CUTOFF=value in determining the maximum
percent difference (MPD) is described in "Computational
Details" later in this section. Caution should be used in changing
the default CUTOFF=value. The empirical threshold ranges found by
the Census Bureau no longer apply when value is changed.
- TDCUTOFF= value
-
gives the percentage value for determining an
excessive difference within a span for the trading day
factors. The default value is 2.0.
The use of the TDCUTOFF=value in determining the maximum
percent difference (MPD) is described in "Computational
Details" later in this section.
Caution should be used in changing
the default TDCUTOFF=value. The empirical threshold ranges found by
the Census Bureau no longer apply when value is changed.
- NOPRINT
-
suppresses all sliding spans reports.
- PRINT
-
prints the summary sliding spans reports S 0 - S 6.E.
- PRINTALL
-
prints the summary sliding spans reports S 0 - S 6.E,
along with detail reports S 7.A - S 7.E.
