## What are the special features of time series data?

Characteristics of Time SeriesThe time series variable (for example, the stock price) may have a trend over time. … The variable may exhibit cyclicity or seasonality. … The data will have serial correlation between subsequent observations.The data will almost always have an irregular component, which is referred to as the White Noise.

## What is series analysis?

Time series analysis is a statistical technique that deals with time series data, or trend analysis. Time series data means that data is in a series of particular time periods or intervals. Time series data: A set of observations on the values that a variable takes at different times. …
