Moments
The Moments table, as shown in Figure 38.9,
includes the following statistics:
- N is the number of nonmissing values, n.
- Sum Wgts is the sum of weights and
is equal to n if no Weight variable is specified.
- Mean is the sample mean,
.
- Sum is the variable sum,
.
- Std Dev is the standard deviation, s.
- Variance is the variance, s^{2}.
- Skewness is the sample skewness, g_{1}.
- Kurtosis is the sample kurtosis, g_{2}.
- USS is the uncorrected sum of squares,
.
- CSS is the sum of squares corrected for the mean,
.
- CV is the percent coefficient of variation,
.
- Std Mean is the standard error of the mean,
. The value is set to missing if vardefDF.
