# automate_LinearRegression
- ### This package is specific to build a Linear Regeression model on the dataset passed as the parameter with its features as well as label to be regressed against. And as such, it is presumed that the analysis and the feature engineering has already been done on the dataset.
- ### This package will standardize the data via StandardScaler() so that all features can be on the same scale and obviously so that the model optimization could increase.
- ### Accuracy of the model built by this package is computed using `adjusted R-squared` metric.
- ### User will also have the flexibility of building the model with regularization modes viz. `Lasso (L1`, `Ridge (L2)` and `ElasticNet` and to compare their accuracies accordingly.
## An Example of How to use:
```python
from automate_LinearRegression import automate_linReg
import pandas as pd
import seaborn as sns
# loading a famous 'Iris' dataset from the seaborn module
df = sns.load_dataset("iris")
df.head()
```
<div>
<table border="1" class="dataframe">
<thead>
<tr style="text-align: right;">
<th></th>
<th>sepal_length</th>
<th>sepal_width</th>
<th>petal_length</th>
<th>petal_width</th>
<th>species</th>
</tr>
</thead>
<tbody>
<tr>
<th>0</th>
<td>5.1</td>
<td>3.5</td>

<td>3.2</td>
<td>1.3</td>
<td>0.2</td>

</tbody>
</table>
</div>
```python
# Assuming `sepal_width` is our label
features = df.drop(columns=['sepal_width', 'species'])
label = df['sepal_width']
```
```python
features.head()
```
