mio::FilterMAD Class Reference

Detailed Description

Median Absolute Deviation. Values outside of median ± 3 σ_MAD are rejected. The σ_MAD is calculated as follows:

$ \sigma_{MAD} = K \cdot \mathop{median_i} \left( \left| X_i - \mathop{median_j} ( X_j ) \right| \right) $ with $ K = \Phi^{-1}; \Phi = 0.6745 $


See http://en.wikipedia.org/wiki/Median_absolute_deviation for more information about the Mean Absolute Deviation. Examples for the io.ini file:

TA::filter1 = mad
TA::arg1 = soft left 1 1800 (1800 seconds time span for the left leaning window)
RH::filter1 = mad
RH::arg1 = 10 600 (strictly centered window spanning 600 seconds and at least 10 points)

get_window (const size_t &index, const std::vector< MeteoData > &ivec)
 A function that cuts out the desired window for the 'index' element within ivec, the window elements are stored into vec_window Calls to this function have to start with index 0, then 1, 2, 3, ... vec_window is not allowed to be changed between two calls. More...
 
bool get_window_specs (const size_t &index, const std::vector< MeteoData > &ivec, size_t &start, size_t &end) const
 A function that computes the start and end for a window for the 'index' element from ivec The principle is too compute the first index that matches the minimum number of points criteria, and the one that matches the minimum time window, then combine them (with the equivalent of OR: we take the MIN index). Afterward, we compute the last index [...] for number of points and the last index [...] for the time window and combine them (with the equivalent of OR: we take the MIN index) or vice versa for right centering.
