The KURTOSIS function computes the statistical kurtosis of an n-element vector. Kurtosis is defined as the degree to which a statistical frequency curve is peaked. KURTOSIS calls the IDL function MOMENT.
Result = KURTOSIS(X [, /DOUBLE] [, /NAN] )
Returns the floating point or double precision statistical kurtosis. If the variance of the vector is zero, the kurtosis is not defined, and KURTOSIS returns
An n-element, floating-point or double-precision vector.
If this keyword is set, computations are performed in double precision arithmetic.
Set this keyword to cause the routine to check for occurrences of the IEEE floating-point values NaN or Infinity in the input data. Elements with the value NaN or Infinity are treated as missing data. (See Special Floating-Point Values for more information on IEEE floating-point values.)
; Define the n-element vector of sample data: x = [65, 63, 67, 64, 68, 62, 70, 66, 68, 67, 69, 71, 66, 65, 70] ; Compute the kurtosis: result = KURTOSIS(x) ; Print the result: PRINT, result
