What is Periodicity?
Periodicity is a fundamental characteristic of time series data in a program which refers to the regular repetition of patterns at fixed intervals. Periodicity means that something repeats after fixed intervals. These regular repetitions of patterns can occur daily, weekly, monthly basis or at any other consistent time interval.
For example, daily traffic patterns and weekly TV programs all present certain periodic patterns.
Periodicity in Time Series Data using R
Periodicity refers to the existence of repeating patterns or cycles in the time series data. Periodicity helps users to understand the underlying trends and make some predictions which is a fundamental task in various fields like finance to climate science.
In time series data, the R Programming Language and its environment for statistical analysis offer a wide range of useful tools and techniques to explore periodicity. Now, we will explore the key functions, libraries, and visualization methods by using R programming language which can help to resolve the uncover hidden patterns in time series data.
