Fast and simple probabilistic data matching package
Keywords: probabilistic match, probabilistic data match, splink

# healmatcher
- `healmatcher` is a simple but fast probabilistic data matching package developed by NYULH HEAL Lab. 
- The package is best optimized for matching healthcare database (e.g. EHR) as it has designed to link Medicaid and Client Database System data.
- `Splink package` is extensively being used to run core linkage processes.
- Currently, the model supports 4 variables (`sex`, `date of birth`, `last 4 digits of ssn`, and `first 2 letters of last name`) to run the linkage process.


## How to install

`pip install healmatcher`


## How to use (example)
```python
# Install package
!pip install healmatcher

# Load package
from healmatcher import hm

# create example dataset
testa = pd.DataFrame({
    'sex':[1,2,1,2,1,2,1,2,1,2],
    'dob':['2012-1-1','2011-12-1','1999-1-1','1998-11-1','2012-11-1','1984-1-1','1982-1-1','1975-1-1','1967-1-1','1954-1-1'],
    'ssn':[1111,2222,3333,4444,5555,6666,7777,8888,9999,1010],
    'ln':["as",'ss','zz','rr','ww','wa','tr','tt','hh','gq'],
    'PROVIDER_NUMBER':[2,1,1,1,1,1,1,1,2,1]
})
testb = pd.DataFrame({
    'sex':[2,2,1,1,1,2,1,2,1,1],
    'dob':['2012-1-1','2001-12-1','1999-1-1','1998-11-1','2012-11-1','1984-1-1','1982-1-1','1975-1-1','1967-1-1','1954-1-1'],
    'ssn':[1111,2222,3333,4444,5555,6666,7777,8888,9999,1010],
    'ln':["as",'ls','zz','rr','wb','wa','tr','tt','ha','gq'],
    'PROVIDER_NUMBER':[2,1,1,1,1,1,1,1,2,1]

# Run matching
hm(
    df_a = testa,
    df_b = testb,
    col_a=['sex','dob','ssn','ln'],
    col_b=['sex','dob','ssn','ln'],
    match_prob_threshold = 0.001,
    iteration = 20,
    model2 = True,
    blocking_rule_for_training_input = 'PROVIDER_NUMBER',
    onetoone = True,
    match_summary = True
)
```

## Updates

- `use_save_model=True` : Load pre-trained model to run matching
- `save_model_path = PATH` : add path to load a model (json format)
- `export_model=True` : argument to save current model
- `export_model_path=PATH` : add path to save current model
