# anticipy

AnticiPy is a tool to generate forecasts for time series. It takes a pandas Series or DataFrame as input, and
returns a DataFrame with the forecasted values for a given period of time.

Features:

* **Simple interface**. Start forecasting with a single function call on a pandas DataFrame.
* **Model selection**. If you provide different multiple models (e.g. linear, sigmoidal, exponential), the tool will
compare them and choose the best fit for your data.
* **Trend and seasonality**. Support for weekly and monthly seasonality, among other types.
* **Calendar events**. Provide lists of special dates, such as holiday seasons or bank holidays, to improve model
performance.
* **Data cleaning**. The library has tools to identify and remove outliers, and to detect and handle step changes in
the data.

It is straightforward to generate a simple linear model with the tool - just call forecast.run_forecast(my_dataframe):

```python
import pandas as pd, numpy as np
from anticipy import forecast, forecast_models
df = pd.DataFrame({'y': np.arange(0., 5)}, index=pd.date_range('2018-01-01', periods=5, freq='D'))
df_forecast = forecast.run_forecast(df, extrapolate_years=1)
print df_forecast.head(12)
```

Output:

```
. date model y is_actuals
0 2018-01-01 y 0.000000e+00 True
1 2018-01-02 y 1.000000e+00 True
