Detailed Description

Mean absolute deviation from mean.

Calculates the mean absolute deviations from the mean

\[ ABSDEV = \sum_i\frac{|x_i-\bar x|}{N} \]

If an optinal mask is given, the calculations are over those locations that correspond to true values in the mask. \( x\) can be single or double precision. The result will have the same numerical precision.
Example

vec = (/ 1., 2, 3., -999., 5., 6. /)
m   = absdev(vec, mask=(vec >= 0.))

See also example in pf_tests directory.

Parameters

[in]	real(sp/dp) :: dat(:)	1D-array with input numbers.
[in]	logical, optional :: mask(:)	1D-array of logical values with size(dat). If present, only those locations in vec corresponding to the true values in mask are used.

Return values

real(sp/dp) :: absdev

Mean absolute deviations from average.

Note

Input values must be floating points.
