### Load Prophet R Package Source: https://facebook.github.io/prophet/docs/index Loads the Prophet library in R. Ensure Prophet is installed before running this command. ```R library(prophet) ``` -------------------------------- ### Import Libraries (Python) Source: https://facebook.github.io/prophet/docs/index Imports the necessary libraries, pandas for data manipulation and Prophet for forecasting. This is a standard starting point for any Prophet project. ```python import pandas as pd from prophet import Prophet ``` -------------------------------- ### Plot Forecast with Plotly (Python) Source: https://facebook.github.io/prophet/docs/index Generates an interactive forecast plot using Plotly. Requires Plotly, notebook, and ipywidgets to be installed. ```python from prophet.plot import plot_plotly, plot_components_plotly plot_plotly(m, forecast) ``` -------------------------------- ### Plot Forecast in R Source: https://facebook.github.io/prophet/docs/index Creates a plot of the Prophet forecast, showing the historical data, forecast line, and uncertainty intervals. ```R plot(m, forecast) ``` -------------------------------- ### Plot Forecast (Python) Source: https://facebook.github.io/prophet/docs/index Visualizes the forecast generated by the Prophet model. The `plot` method displays the predicted values against the historical data. ```python fig1 = m.plot(forecast) ``` -------------------------------- ### Instantiate and Fit Prophet Model (Python) Source: https://facebook.github.io/prophet/docs/index Creates an instance of the Prophet model and fits it to the prepared historical data. The `fit` method trains the model to learn patterns from the time series. ```python m = Prophet() m.fit(df) ``` -------------------------------- ### Plot Prophet Components in R Source: https://facebook.github.io/prophet/docs/index Visualizes the individual components of the Prophet forecast, such as trend, weekly seasonality, and yearly seasonality. ```R prophet_plot_components(m, forecast) ``` -------------------------------- ### Plot Forecast Components with Plotly (Python) Source: https://facebook.github.io/prophet/docs/index Generates interactive plots of forecast components using Plotly. This provides a detailed breakdown of seasonality and trend. ```python plot_components_plotly(m, forecast) ``` -------------------------------- ### Create Future Dataframe for Forecasting in R Source: https://facebook.github.io/prophet/docs/index Generates a dataframe with future dates for making predictions. Includes historical dates by default for in-sample evaluation. ```R future <- make_future_dataframe(m, periods = 365) tail(future) ``` -------------------------------- ### Plot Forecast Components (Python) Source: https://facebook.github.io/prophet/docs/index Visualizes the components of the forecast, such as trend, seasonality, and holidays. The `plot_components` method helps in understanding the different factors contributing to the forecast. ```python fig2 = m.plot_components(forecast) ``` -------------------------------- ### Load and Inspect Data (Python) Source: https://facebook.github.io/prophet/docs/index Loads a CSV dataset from a URL into a pandas DataFrame and displays the first few rows. This step is crucial for understanding the structure and content of the time series data. ```python df = pd.read_csv('https://raw.githubusercontent.com/facebook/prophet/main/examples/example_wp_log_peyton_manning.csv') df.head() ``` -------------------------------- ### Fit Prophet Model in R Source: https://facebook.github.io/prophet/docs/index Fits the Prophet time series model to the provided historical dataframe. The dataframe must have 'ds' and 'y' columns. ```R m <- prophet(df) ``` -------------------------------- ### Generate Forecast in R Source: https://facebook.github.io/prophet/docs/index Predicts future values using the fitted Prophet model and the future dataframe. The output includes forecast ('yhat') and uncertainty intervals. ```R forecast <- predict(m, future) tail(forecast[c('ds', 'yhat', 'yhat_lower', 'yhat_upper')]) ``` -------------------------------- ### Load Data for Prophet in R Source: https://facebook.github.io/prophet/docs/index Reads a CSV file from a specified URL into an R dataframe. The dataframe must contain 'ds' (date) and 'y' (numeric value) columns for Prophet. ```R df <- read.csv('https://raw.githubusercontent.com/facebook/prophet/main/examples/example_wp_log_peyton_manning.csv') ``` -------------------------------- ### Create Future Dataframe (Python) Source: https://facebook.github.io/prophet/docs/index Generates a dataframe containing future dates for which predictions will be made. The `make_future_dataframe` method extends the historical data by a specified number of periods. ```python future = m.make_future_dataframe(periods=365) future.tail() ``` -------------------------------- ### Generate Forecast (Python) Source: https://facebook.github.io/prophet/docs/index Predicts future values based on the fitted Prophet model and the future dataframe. The `predict` method returns a dataframe with forecasts, including `yhat` (predicted value) and uncertainty intervals. ```python forecast = m.predict(future) forecast[['ds', 'yhat', 'yhat_lower', 'yhat_upper']].tail() ``` === COMPLETE CONTENT === This response contains all available snippets from this library.
