Misc code snippets I sometimes need and always have to look up how it works...


## linear_regression.py

Calculate the linear regression on two columns of a data frame. The resulting
object has the function `predict()` to calculate x or y values for a given 
counterpart.

```python
    from linear_regression import linear_regression
    
    df = pd.DataFrame({"temperature":[...], "signal":[...]})

    regression = linear_regression(df, x="temperature", y="signal")

    repr(regression) == "Regression(intercept=1, coefficient=3, score=0.9998)"

    regression.predict(x=3) == 10
    regression.predict(y=7) == 2
```
