| | 71 | Comparing the state vector or parts of it with independent values, e.g. independent observations provides insights into the assimilation skill. The routine `PDAF_diag_diffstats` computes 6 statistics comparing two input vectors (where one can be the state vector and the second a vector of indpendent values). The statistics are the correlation of both vectors, their centered root-mean square difference, their mean bias, their mean absolute difference, and the standard deviation, i.e. variability, of each vector. These values can be used, e.g. to plot Taylor diagrams. |
