Prophet in r

Implements a procedure for forecasting time series data based on an additive model where non-linear trends are fit with yearly, weekly, and daily seasonality, plus holiday effects. It works best with time series that have strong seasonal effects and several seasons of historical data. Prophet is robust to missing data and shifts in the trend, and typically handles outliers well. Created by DataCamp.

Plot a performance metric vs. Cross validation produces a collection of out-of-sample model predictions that can be compared to actual values, at a range of different horizons distance from the cutoff.

This computes a specified performance metric for each prediction, and aggregated over a rolling window with horizon. Plot the components of a prophet forecast. Prints a ggplot2 with whichever are available of: trend, holidays, weekly seasonality, yearly seasonality, and additive and multiplicative extra regressors. Dataframe with seasonality features. Includes seasonality features, holiday features, and added regressors.Hence, using data forecasting tools are one of the common tasks data professionals are being asked to take on.

Available both for R and Python, this is a relatively easy to implement model with some much needed customization options.

This code flow is heavily inspired from the official package users guide. We will use an open data set extracted from wikishark holding daily data entrances to LeBron James Wikipedia article page. Next, we will build daily predictions based on historical data. For our code example we will transform the data and use the log of entrances. This will help us make sense of the prediction visualizations. We can see the data is from —01—01 and up to —12—31 with some yearly seasonality peaks from April thorough June.

Like machine learning models the first command fits a model on the dataframe and next will deploy the model using the predict command in order to receive predictions for the length of days required. The out of the box visualizations of the prophet package are quite nice with predefined tick marks, data points and uncertainty intervals.

This is one of the advantages of this open source package, no need for extra customization and the first result is fast and good enough for most needs. Using this graph we spot the yearly trend and seasonality much clearer and how these are used for making predictions.

The forecast object holds the raw data with the predicted value by day and uncertainty intervals. It is also possible to access the prediction trends and seasonality components with:. Showing the overall trend, weekly and yearly seasonality. The model at this point recognizes the yearly seasonality which returns every year. On a side note, LeBron James currently holds the record for 6 consecutive years of playing the NBA playoffs starting with Miami and continuing with the Cavaliers.

So we should expect the same seasonality year after year. Adding holidays and events is a major advantage of the package. Firstly by making the predictions more accurate and allowing the user to take into considerations known future events. The developers had made this customization much easier than prior time series packages in which events and holidays should have been manually changed or ignored in order to make predictions.

Think of an e-commerce website that can add all reoccurring campaigns and promotions and set revenue goals based on known future campaign dates. Adding events and holidays is done by creating a new dataframe in which we pass the dates of begging or ending of the events and the length of the days.

Using the lower and upper window parameters the user can set the length of the holiday. Those mappings will be row binded to a single object and passed in holidays parameter. Notice the model better predicts the values during the peaks. Printing out he components again will show the added row of holidays effect on prediction. Theoretically you can map many events which are critical for the business and get better predictions.Click to learn more about author Steve Miller.

With that engagement, the challenge was forecasting hundreds of daily time series, each with several years of historical data. Patterns manifested included trend and multiple seasons. Predictions were desired over an entire year, and models were to be updated weekly with the latest data. I started the work with a pretty standard bag of statistical forecasting tricks, including moving averages, seasonal and trend decomposition, exponential smoothing such as Holt Winters, ARIMA, and even a few econometric alternatives.

Alas, after none of these attempts even closely nailed it, I turned to traditional regression and more modern machine learning approaches though, given autocorrelation of disturbances, these are generally considered anathema for forecasting by statistical purists.

I was getting desperate, however. A statistical consolation was that I was just interested in the quality of predictions, not overall model purity. It is based on an additive model where non-linear trends are fit with yearly and weekly seasonality, plus holidays. It works best with daily periodicity data with at least one year of historical data.

Prophet is robust to missing data, shifts in the trend, and large outliers. Could this be what I needed years ago? Quebec represents counts of 14 years of daily newborn deliveries in the Canadian province.

It served nicely for simulating my digital marketing challenges and I figured it could now help me put prophet through its paces as well. The remainder of this post examines the results of several modeling exercises in R against the Quebec data divided into train with 13 years and test with one.

Create train and test data. Define two little functions to compute root mean square error rmse and mean absolute percentage error mape of actual vs predicted a la forecast for evaluating forecast model performance.

Lower is better.

Now start fitting basic lm linear models. The first regresses dailybirths y on a cubic spline of the integer date ds to capture trend. Compute the rmse and mape against the training and test data.

Not surprisingly, the stats for train are better than for test. Next run a model of dailybirths on a day of the week factor to capture intra-week seasonality. This model appears to do better than the first on the preformance metrics, indicating significant day of the week seasonality.Our monthly page magazine features prophetic articles on Bible prophecy, the second coming of Jesus Christ and the end-times.

Now its time to start forecasting. With Prophet, you start by building some future time data with the following command:. If you take a quick look at the data using.

That looks pretty good. Since we are working with monthly data, Prophet will plot the trend and the yearly seasonality but if you were working with daily data, you would also see a weekly seasonality plot included.

From the trend and seasonality, we can see that the trend is a playing a large part in the underlying time series and seasonality comes into play more toward the beginning and the end of the year.
