How to test for outliers in Matlab?

By default, an outlier is a value that is more than three scaled median absolute deviations (MAD) from the median. TF = isoutlier( A , method ) specifies a method for detecting outliers. For example, isoutlier(A,"mean") returns true for all elements more than three standard deviations from the mean.

How do you find the outliers of a box plot in Matlab?

boxplot draws points as outliers if they are greater than q3 + w × (q3 – q1) or less than q1 – w × (q3 – q1), where w is the multiplier Whisker , and q1 and q3 are the 25th and 75th percentiles of the sample data, respectively.

How do you remove outliers from a graph in Matlab?

Remove Outliers Interactively

Click a point that you want to exclude in the fit plot or residuals plot. Alternatively, click and drag to define a rectangle and remove all enclosed points.
