Learning data science on your own is tough...

...(ahem, it took me 6 years)

So here's some help.

5 Free Books to Cut Your Time In HALF.

Let's go! 🧡

#datascience #rstats #R Image
1. Mastering #Spark with #R

This book solves an important problem- what happens when your data gets too big?

For example, analyzing 100,000,000 time series.

You can do it in R with the tools covered in this book.

2. Geocomputation with #R

Interested in #Geospatial Analysis?

This book is my go-to resource for all things geospatial.

This book covers:
-Making Maps
-Working with Spatial Data
-Applications (Transportation, Geomarketing)

3. Tidy Finance with #R

What tools exist in R for #Finance?
And how do I use them?

Answers to these questions are covered in this book!

P.S.- This book uses my R package, #tidyquant

5. #Forecasting Principles and Practice

This is the best β€œtheory” book on #timeseries analysis and forecasting.

Topics Covered:
- ARIMA,
- Exponential Smoothing,
- TimeSeries Decomposition
- A lot more!

Python has powerful time series libraries.

Case in point: skforecast

Let me explain: Image
Skforecast is a Python library for time series forecasting using machine learning models.

Skforecast works with any regressor compatible with the scikit-learn API, including popular options like LightGBM, XGBoost, CatBoost, Keras, and many others. Image
skforecast shines with probabilistic forecasting.

When trying to anticipate future values, most forecasting models try to predict what will be the most likely value.

This is called point forecasting.

My favorite R package for ultra-fast exploratory analysis: Image
The R package is called correlationfunnel.

Yes, I built it.
What correlationfunnel does is:

* Speeds Up Exploratory Data Analysis

* Improves Feature Selection

* Gets You To Business Insights Faster Image

The best beginner book on time series?

FPP: Forecasting Principles and Practice

Let's dive in: Image
Some may consider FPP the bible of time series.

I agree.

Start with FPP Version 2 or 3, and you won't go wrong.

This is what I like:
1. Time Series Visualizations

There's no better intuition for time series than a visualization.

- Time Plots
- Seasonal Plots
- ACF Plots

All are absolutely critical to understanding time series patterns. Image

BEAST: A Bayesian Ensemble Algorithm for Change-Point Detection and Time Series Decomposition in R

Let's explore: Image
1. What is BEAST?

BEAST stands for Bayesian Estimator of Abrupt change, Seasonality, and Trend.

But what does that mean?
According to the authors, BEAST is a fast, generic Bayesian model averaging algorithm to decompose time series or 1D sequential data into individual components, such as abrupt changes, trends, and periodic/seasonal variations

I used to struggle with working with Time Series.

After 10 years, I mastered it.

Then I spent 3 years making this R package so you can too: Image
The R package is timetk. I built it to make your life easier when working with Time Series:

- Plotting (Visualization)
- Data Wrangling
- Correlation
- Seasonality
- Imputation
- Outliers (Anomalies)
- Feature engineering
- Cross Validation
I'll focus on Time Series Plotting today.

1. Plotting Time Series: Use plot_time_series() Image

R is crazy good at forecasting.

Just learn this R package: Image
The R package is modeltime (and yes, I created it).

Modeltime's goal is to make high-performance time series analysis easier, faster, and more scalable in R. Image
1. How modeltime works

Modeltime leverages the Tidymodels framework (like scikit learn but in R) to open up:

- ARIMA
- Exponential Smoothing
- Prophet
- Linear Regression
- Elastic Net
- XGBoost
(and more) Image
