Time-series forecasting is one of the important applications for Machine Learning and Deep Learning. There are multiple models which can be used for time series forecasting like Arima, Prophet, Holt-Winters, etc. Multiple Python libraries can be used for loading these models and using them but they are not user-friendly and are difficult to use.

PMDArima is an open-source Python library that is used for time series forecasting and also helps in creating time series plots. It is easy to use and generates time-series forecast on the ARIMA model.

In this article, we will explore PMDArima and generate a time-series forecast using it.

Let’s get started…

Installing required libraries

We will start by installing a PMDArima library by using pip. For downloading the data we will use the yfinance library. The command given below will do that.

Downloading dataset

For downloading the dataset we will use Yahoo finance. You can follow the code given below for downloading the data for the particular ticker and can also follow the article to understand yfinance and its functionalities.

Data Preprocessing & Modelling

Next, we will preprocess the data by splitting it into test and train. Also, we will define the function for forecasting.

Visualizing Actual Vs Predicted Values

In this step, we will visualize the actual vs. predicted values given by the model. Similarly, we will also plot the confidence intervals with the predicted values.

▲Visualization(來源:By Author)

Here we can clearly visualize the predicted and actual values and use them for analysis. Go ahead try this with different datasets and perform forecasting and visualizations using PMDArima. In case you find any difficulty please let me know in the response section.
