PRINT Subcommand (RATIO STATISTICS command)
PRINT
displays
optional output. If no PRINT
subcommand
is specified, only a case processing summary table is displayed by
default.
- AAD
- Average absolute deviation. The result of summing the absolute deviations of the ratios about the median and dividing the result by the total number of ratios.
- BCOC(low,high) …)
- Coefficient of concentration. The percentage of ratios that fall into an interval. Pairs of low and high values enclosed in parentheses specify the intervals.
- CIN(a)
- Confidence interval. Specifying this keyword displays confidence intervals for the mean, median, and weighted mean (if those statistics are requested). Specify a value greater than or equal to 0 and less than 100 as the confidence level.
- COD
- Coefficient of dispersion. The result of expressing the average absolute deviation as a percentage of the median.
- COV
- Coefficient of variation. Alias for MNCOV.
- MAX
- Maximum. The largest ratio.
- MDCOV
- Median-centered coefficient of variation. The result of expressing the root mean squares of deviation from the median as a percentage of the median.
- MEAN
- Mean. The result of summing the ratios and dividing the result by the total number ratios.
- MEDIAN
- Median. The value such that number of ratios less than this value and the number of ratios greater than this value are the same.
- MIN
- Minimum. The smallest ratio.
- MNCOV
- Mean-centered coefficient of variation. The result of expressing the standard deviation as a percentage of the mean.
- N
- Sample size. Weighted if weighting is in effect.
- PRB
- Price-related bias. An index of whether assessment to price ratios are systematically higher or lower for higher-priced properties. Regresses percentage differences in assessment ratios from the median ratio on the base 2 logarithms of value proxy measures calculated as the averages of sales prices and the ratios of assessed values to the median ratio. Gives the percentage change in assessment ratios for a 100 percent change in value.
- PRD
- Price-related differential. Also known as the index of regressivity, the result of dividing the mean by the weighted mean.
- RANGE
- Range. The result of subtracting the minimum ratio from the maximum ratio.
- STDDEV
- Standard deviation. The result of summing the squared deviations of the ratios about the mean, dividing the result by the total number of ratios minus one, and taking the positive square root.
- WCOC(value list)
- Coefficient of concentration. The percentage of ratios that fall within the specified percentage of the median. Specify a list of values that are greater than 0 and less than 100.
- WGTMEAN
- Weighted mean. The result of dividing the mean of the numerator by the mean of the denominator. It is also the mean of the ratios weighted by the denominator.
Example
RATIO STATISTICS appraise WITH price BY county
/PRINT = BCOC((0.5,0.9) (1.3,1.5)) WCOC(15 30 45) MEDIAN PRD.
- The median ratios and priced related differentials at each category of county are displayed. The overall median ratio and the overall price-related differential are also displayed.
- Five coefficients of concentration are also displayed. The first two
COC
are percentages of ratios that fall into the intervals: (0.5, 0.9) and (1.3, 1.5). The next threeCOC
are percentages of ratios that fall within 15% of the median, 30% of the median, and 45% of the median.
