Outliers identified by outval will be coded to a certain number of units higher/lower than the greatest nonoutlier value. Default is 0 units. |
Details
Recodes outliers using Tabachnick and Fidell's (2013) criteria. A variable is standardized and values that are greater/less than or equal to a specified outlier value (specified in standard deviations; default 3.29SD) are recoded to a certain number of units (default 0) higher/lower than the greatest nonoutlier value. Disregards 'NA' values.
Value
