Owning Palette: Probability & Statistics VIs
Requires: Base Development System
Computes the skewness and kurtosis of the input sequence X.
Skewness is a measurement of symmetry. Kurtosis is the peak measurement of a distribution.

X is the input sequence. If X is empty, skewness and kurtosis are NaN. | |||||
Weighting specifies whether the input sequence X is a complete population or a random sample taken from a population.

|||||
skewness returns the symmetrical measurement of the input sequence X. | |||||
kurtosis returns the peak measurement of the input sequence X. | |||||
error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster. |
A negative value of skewness indicates that the left side of the probability density function is longer than the right side. A positive value of skewness indicates that the right side of the probability density function is longer than the right side.
The following front panel image shows negative skewness.
The following front panel image shows positive skewness.
When determining kurtosis, normal distribution has a kurtosis value of 3. A kurtosis value of less than 3 indicates a flatter distribution than normal. A kurtosis value of greater than 3 indicates a sharper distribution than normal. The following front panel image shows three distributions with kurtosis values of 6, 3, 1.8.
