[Unreleased]

[1.0.3] - 2020-02-04

Fixed

  • Bug whereby Splink lowercased case expressions, see here

[1.0.2] - 2020-02-02

Changed

  • Improve estimate comparison charts, including tooltips and better labels

[1.0.1] - 2020-01-31

Changed

  • Added mousewheel zoom to bayes factor chart
  • Added mousewheel zoom to splink score histogram
  • Update estimate comparison chart to use different shapes for different estimates, making it possible to distinguish overlapping symbols

Fixed

  • m and u history charts now display barchart correctly

[1.0.0] - 2020-01-20

Added

  • Charts now feature improved tooltips, and have a cleaner appearance. Many are now zoomable
  • Charts now display better in Jupyter Lab, especially the html file produced by all_charts_write_html_file()
  • m and u probabilities charts can now be produced from Settings objects
  • The user can now combine settings objects using ModelCombiner from splink.combine_models

Changed

A number of backwards incompatible changes have been made for Splink 1.0.

  • The main Splink API is different. Instead of Splink(...,df=df) for dedupe and Splink(...,df_l=df_l,df_r=df_r) for linking, the user provides an agument df_or_dfs, which is either a single DataFrame or a list of DataFrames. This allows linking n>2 datasets.
  • When linking multiple dataframes, the user must now include a source_dataset column (default name source_dataset, configurable via source_dataset_column_name in the settings dict)
  • The Params class is now called Model in the model.py module.
  • The on-disk (json) format of the Model object has changed and is incompatible with Params
  • The new Model class now uses the same representation for parameters as the Settings object, reducing duplicate code. Internal functions now have settings or model as function arguments, never both.
  • Vega lite chart definitions now stored in json files in splink/files/chart_defs
  • All case statement generation functions are now consistently named, with all names starting sql_gen_case_stmt_
  • Fixed case_statements.sql_gen_case_smnt_strict_equality_2 which previously behaved differently to all other case functions
  • All case statements now have a default threshold of exact equality on their top gamma level

Fixed

Removed
