A Practical Approach to Timeseries Forecasting Using Python - Trend Using Moving Average Filter

The video tutorial covers fitting a trend using a linear regression model in Python's scitlearn library. It explains importing necessary libraries, setting up plot configurations using matplotlib, and plotting trends through automatic decomposition and moving averages. The tutorial also demonstrates implementing linear regression to predict trends in time series data, providing a comprehensive guide to analyzing trends using different methodologies.

What is the primary purpose of using a linear regression model in trend analysis?

• To determine the median of a dataset

• To identify seasonal patterns

• To calculate the average of a dataset

• To predict future values based on past data

Which library is used for implementing linear regression in the tutorial?

• Scitlearn

• Pandas

• Matplotlib

• NumPy

What is the first step in setting up the plot layout for visualizing trends?

• Running the linear regression model

• Importing data

• Setting the figure size

• Calculating moving averages

How many subplots are created for visualizing the trends, moving averages, and linear regression?

• Two

• Three

• Four

• Five

What is the step size used for calculating the moving average in the tutorial?

• 6

• 8

• 10

• 12

What is the purpose of reshaping the X values in the linear regression implementation?

• To convert them into a matrix

• To ensure they are in a series format

• To calculate their mean

• To sort them in ascending order

What command is used to display the plots after they are created?

• plt.render()

• plt.show()

• plt.display()

• plt.plot()

What is the main focus of the next section after discussing trend analysis?

• Advanced regression techniques

• Data cleaning

• Time series forecasting

• Seasonality comparison

Which method is used to predict the trend in the linear regression model?

• model.evaluate()

• model.estimate()

• model.calculate()

• model.predict()

What is the significance of the straight line in the linear regression plot?

• It highlights the seasonal pattern

• It indicates the trend in the time series

• It shows the maximum value

• It represents the average value
