public enum LeveneTestLocationMeasure
Remarks
Levene's test for homogeneity of variances assumes that the underlying populations of the samples have a normal distribution. A specific choice of measure for central tendency can make the test more robust when the data is not normal.
Members
Median | 0 | The median is used. This is the default, and gives better results when the data is skewed. |
TrimmedMean | 1 | The 10% trimmed mean is used. This gives better results when the data is heavy-tailed. |
Mean | -1 | The mean is used. This works best for normal data. |
