There are two main types of time series analysis: univariate and multivariate.

• Univariate time series analysis is used to analyze a single time series. This can be used to identify trends, patterns, and seasonality in the data.
• Multivariate time series analysis is used to analyze two or more time series. This can be used to identify relationships between the different time series.

Time series analysis can be used to answer a variety of questions, such as:

• What are the trends in my data?
• Are there any seasonal patterns in my data?
• What are the relationships between the different time series?
• How can I predict future values of the time series?
