1328 RATIO STATISTICS<br />

• Keywords EXCLUDE and INCLUDE are mutually exclusive. Only one of them can be<br />

specified once.<br />

EXCLUDE Exclude both user-missing and system-missing values. This is the default.<br />

INCLUDE User-missing values are treated as valid. System-missing values cannot be<br />

included in the analysis.<br />

OUTFILE Subcommand<br />

OUTFILE saves the requested statistics to an external file in SPSS data format.<br />

• The requested statistics are saved in a single record in the external file.<br />

• If a group variable has been specified, the requested statistics at each category of the<br />

group variable will also be saved as additional records in the external file.<br />

• A valid (server side) filename must be specified within a pair of parentheses after the<br />

subcommand name.<br />

The following statistics are available.<br />

AAD Average absolute deviation. The result of summing the absolute<br />

deviations of the ratios about the median and dividing the result by the<br />

total number of ratios.<br />

BCOC (low,high) …) Coefficient of concentration. The percentage of ratios that fall into an<br />

interval. Pairs of low and high values enclosed in parentheses specify<br />

the intervals.<br />

CIN(a) Confidence interval. Specifying this keyword displays confidence<br />

intervals for the mean, median, and weighted mean (if those statistics<br />

are requested). Specify a value greater than or equal to 0 and less than<br />

100 as the confidence level.<br />

COD Coefficient of dispersion. The result of expressing the average<br />

absolute deviation as a percentage of the median.<br />

MAX Maximum. The largest ratio.<br />

MDCOV Median-centered coefficient of variation. The result of expressing the<br />

root mean squares of deviation from the median as a percentage of the<br />

median.<br />

MEAN Mean. The result of summing the ratios and dividing the result by the<br />

total number ratios.<br />

MEDIAN Median. The value such that number of ratios less than this value and<br />

the number of ratios greater than this value are the same.<br />

MIN Minimum. The smallest ratio.<br />

MNCOV Mean-centered coefficient of variation. The result of expressing the<br />

standard deviation as a percentage of the mean.
