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.
There are two basic approache s that can be. used in dealing with outliers and influential. points. This report considers the approach of. having an arsenal of tools for isolating these. important points for further study, with the. possibility of deleting some or all of the points. from the analysis.
