;
;
;
; NAME:
; meanabsdev
;
; PURPOSE:
; Calculates the mean absolute deviation of the input data
;
;
; CATEGORY:
; Mathematics: Statistics
;
; CALLING SEQUENCE:
; Result=meanabsdev(x)
;
;
; KEYWORD PARAMETERS:
; DOUBLE : Keyword for double precision calculation
; NAN : Flag to ignore IEEE Floating point NaN
;
; OUTPUTS:
; Result is the mean absolute deviation of input data
;
;
; RESTRICTIONS:
; The input x needs to be an array of numbers (i.e not strings,
; struct, ptr, object)
;
; PROCEDURE:
; mean absolute deviation = (1/N) sum(abs(x-mean(x))),
; Uses the MOMENT function
;
; EXAMPLE:
; a=findgen(100)
; result=meanabsdev(a)
; print, result
; 25.0000
