Body voltage testing â also called skin voltage testing â is the most sensitive, accurate and helpful method available to detect electric fields. This is a very important measurement, especially for sensitive individuals.
An outlier can be created by a shift in the location. (mean) or in the scale (variability) of the process. Though an observation in a particular sample might be a. candidate as an outlier, the process might have shifted. Sometimes, the spurious result is a gross recording. error or a measurement error.
Re: Removing outliers using SAS. Use proc standard. This will give you the standard normal distribution of your variables. Remove the variables outside the range of -3 to 3.This only treats univariate outliers. For multivariate outliers look at Mahalanobis distances. This can be done using proc princomp using std option in the statement.e: Removing outliers using SAS. Use proc standard. This will give you the standard normal distribution of your variables.
