+Difficulty Index
+****************
+
+Description
+===========
+
+This module is used to calculate the difficulty of a decision based on a set of forecasts, 
+such as an ensemble, for quantities such as wind speed or significant wave height as a 
+function of space and time.
+
+Example
+=======
+
+An example Use-Case for running Difficulty Index for Wind Speed can be found in the `METplus documentation <https://metplus.readthedocs.io/en/latest/generated/model_applications/medium_range/UserScript_fcstGEFS_Difficulty_Index.html#sphx-glr-generated-model-applications-medium-range-userscript-fcstgefs-difficulty-index-py>`_.
+
+Decision Difficulty Index Computation
+=====================================
+
+Consider the following formulation of a forecast decision difficulty index:
+
+  .. math :: d_{i,j} = \frac{A(\bar{x}_{i,j})}{2}(\frac{(\sigma/\bar{x})_{i,j}}{(\sigma/\bar{x})_{ref}}+[1-\frac{1}{2}|P(x_{i,j}\geq thresh)-P(x_{i,j}<thresh)|])
+
+where :math:`\sigma` is the ensemble standard deviation, :math:`\bar{x}` is the ensemble mean, 
+:math:`P(x_{i,j}\geq thresh)` is the ensemble (sample) probability of being greater than or equal 
+to the threshold, and  :math:`P(x_{i,j}<thresh)` is the ensemble probability of being less than 
+the threshold. The :math:`(\sigma/\bar{x})` expression is a measure of spread normalized by the 
+mean, and it allows one to identify situations of truly significant uncertainty. Because the 
+difficulty index is defined only for positive definite quantities such as wind speed or significant 
+wave height, division by zero is avoided. :math:`(\sigma/\bar{x})_{ref}` is a (scalar) reference 
+value, for example the maximum value of :math:`(\sigma/\bar{x})` obtained over the last 5 days as 
+a function of geographic region.
+
+The first term in the outer brackets is large when the uncertainty in the current forecast is 
+large relative to a reference. The second term is minimum when all the probability is either 
+above or below the threshold, and maximum when the probability is evenly distributed about the 
+threshold. Therefore, it penalizes the split case, where the ensemble members are close to evenly 
+split on either side of the threshold. The *A* term outside the brackets is a weighting to account 
+for heuristic forecast difficulty situations. Its values for winds are given below.
+
+| A = 0 if :math:`\bar{x}` is above 50kt
+| A = 0 if :math:`\bar{x}` is below 5kt
+| A = 1.5 if :math:`\bar{x}` is between 28kt and 34kt
+| A = :math:`1.5 - 1.5[\frac{\bar{x}(kt)-34kt}{16kt}]` for 34kt :math:`\leq\bar{x}\leq` 50kt
+| A = :math:`1.5[\frac{\bar{x}(kt)-5kt}{23kt}]` for 5kt :math:`\leq\bar{x}\leq` 28kt
+
+  .. _difficulty_index_fig1:
+
+  .. figure:: figure/weighting_wind_speed_difficulty_index.png
+
+     Weighting applied to wind difficulty index.
+
+The weighting ramps up to a value 1.5 for a value of *x* that is slightly below the threshold. 
+This accounts for the notion that a forecast is more difficult when it is slightly below the threshold 
+than slightly above. The value of *A* then ramps down to zero for large values of 
+:math:`\bar{x}_{i,j}`.
+
+To gain a sense of how the difficulty index performs, consider the interplay between probability of 
+exceedance, normalized ensemble spread, and the mean forecast value (which sets the value of 
+*A*) shown in Tables 3.1-3.3. Each row is for a different probability of threshold exceedance, 
+:math:`P(x_{i,j} \geq thresh)`, each column is for a different value of normalized uncertainty, 
+quantized as small, :math:`(\sigma/\bar{x})/(\sigma/\bar{x})_{ref}=0.01`, medium, 
+:math:`(\sigma/\bar{x})/(\sigma/\bar{x})_{ref}=0.05`, and large, 
+:math:`(\sigma/\bar{x})/(\sigma/\bar{x})_{ref}=1.0`. Each box contains the calculation of 
+:math:`d_{i,j}` for that case.
+
+When :math:`\bar{x}` is very large or very small the difficulty index is dominated by *A*. 
+Regardless of the spread or the probability of exceedance the difficulty index takes on a value near 
+zero and the forecast is considered to be easy (:numref:`table_1`).
+
+When :math:`\bar{x}` is near the threshold (e.g. 25kt or 37kt), the situation is a bit more complex 
+(:numref:`table_2`). For small values of spread the only interesting case is when the probability is 
+equally distributed about the threshold. For large spread, all probability values deserve a look, and 
+the case where the probability is equally distributed about the threshold is deemed difficult.
+
+When :math:`\bar{x}` is close to but slightly below the threshold (e.g. between 28kt and 34kt), 
+almost all combinations of probability of exceedance and spread deserve a look, and all values of the 
+difficulty index for medium and large spread are difficult or nearly difficult (:numref:`table_3`).
