v0.5.0

• Fixed bug with incorrect behaviour in TIDE algorithm: if candidate point was idx_base, it was skipped.
• Changed logic for point selection and brackets.
  Now for positive trend we use the candidate point (idx_cand) and (a,b] brackets; for negative - idx_cand+1 and [a,b) brackets
• Changed text brackets for -inf, +inf borders to always be '(' or ')'
• Visual improvements for plots
• Added sample_rate in stats for convenience
• Rewrited some docs
• Added 'tide' mode for categorical bins handling

v0.4.0

• Add parameter 'handle_unknown' to 'TIDE.transform' which specifies behavior on how to transform values that are not covered by fitted bins
• One more attempt to fix PSI calculation when there are no continuous values in column

v0.3.4

• Add basic tests for event rate calculation, as well as WoE, IV, PSI
• Fix bug of PSI calculation when continuous index not provided explicitly

v0.3.3

• Fix PSI calculation when period column has string format
• Fix reset functionality

v0.3.2

• Change PSI to PSI_base and PSI_seq in stats.
  PSI_base compares periods with first one, while PSI_seq does period by period sequentially (which was the initial PSI realization)
• Plots improvement: add IV to header, add new PSIs.

v0.3.1

• Fix case when the missing_strategy is "worst_bin" or "best_bin", but there is no missing values present in column

v0.3.0

• Add missing value merge to worst/best continuous bins

v0.2.1

• Fix chi-merge for tiny categorical bins
• Add warning for columns with >= 100 categorical bins. As chi-merge for categorical bins has O(n^2) complexity, performance may be poor in case when one chooses cat_strategy='chi-squared'

v0.2.0

• Add Chi-merge for categorical bins
• Add min_er_delta which forces the minumum difference between event rates in bins across all periods
• Change min_sample_rate logic: now the denominator corresponds to the size of full x column (previously it was of continuous part only)
• Minor fixes and improvements

v0.1.2

• Fix issue with incorrect IV calculation for fully categorical variables
• Remove unnecessary debug prints
