  isLower = TRUE, plot = FALSE)

outlier.cutoff(x, lBound = NULL, uBound = NULL)

Arguments

x

An integer/numeric vector used as the input

alpha, z.cutoff

alpha is the percentage of the standard deviation from the center of the data. z.cutoff is the standardized z-score value. They are used as the distribution based thresholds.

isUpper, isLower

logical scalars indicating whether the outliers are checked at upper or lower side of the distribution.

plot

logical scalar indicating whether to visualize the outlier detection results.

...

other arguments to be passed to qoutlier function,currently it is ignored.

lBound, uBound

Numeric scalars used as cutoff threshold for either lower limit or upper limit

Details

These different outlier detection functions are used together with qaCheck method to perform outlier checks.

Value

a logical vector with the same length of input vector,indicating whether each entry of the input is a outlier.
