## 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
|
|
|
|
|
```
