Permetrics

Change models

+ Add Evaluator class, the base class for all metrics
+ Rename class Metrics in regression to RegressionMetric
+ Rename class Metrics in classification to ClassificationMetric
+ Update input parameters in both RegressionMetric and ClassificationMetric
+ Update input parameters in all metric functions
+ Add docstring for all methods
+ Merge all singleloss metrics to RegressionMetric
+ Update examples
+ Add new documents and website

---------------------------------------------------------------------

Fix bugs

+ Fix bugs of R2S, MAPE and some other functions

---------------------------------------------------------------------

Change models

+ Change class Metrics in regression.py to take both OOP style and Functional style.
+ Add some new metrics including
23. PCD: Prediction of Change in Direction
24. E: Entropy
25. CE: Cross Entropy
26. KLD: Kullback Leibler Divergence
27. JSD: Jensen Shannon Divergence
28. VAF: Variance Accounted For
29. RAE: Relative Absolute Error
30. A10: A10 Index
31. A20: A20 Index
32. NRMSE: Normalized root Mean Square Error
33. RSE: Residual Standard Error

Change others

+ Examples:
+ Update examples of old metrics
+ Add examples for new metrics

---------------------------------------------------------------------

Change models
+ Add some new methods to regression.py
21. Gini coefficient
+ Based on other code (Mathlab code)
+ Based on wiki version
22. Mean Log Likelihood

+ Add new class SingleLoss for numbers-verse-numbers, the output is numbers (not single number as regression.py)
1. Relative error
2. Absolute error
3. Squared error
4. Squared log error
5. Log likelihood

+ Add new class for classification metrics
1. Mean Log Likelihood


Change others
+ Examples:
+ Add examples
+ Add documents

---------------------------------------------------------------------

Change models
+ Add some new methods:
18. Kling-Gupta Efficiency (KGE)
19. Deviation of Runoff Volume (DRV)
20. (Pearson’s Correlation Index)**2 or R2s (or R2)

Change others
+ Examples:
+ Add examples

---------------------------------------------------------------------

Change models
+ Add method for multiple metrics called at the same time
+ Call by list of function names (default function parameters)
+ Call by list of function names and parameters (can change function parameters)
Change others
+ Examples:
+ Add all examples for all metrics
+ Add example for multiple metrics called at the same time
+ Documents: Add all documents for all metrics
