The first step is to create a time series object to conduct time series analysis in R. Suppose we have the data in a vector, matrix, or data frame. We need to use thets()function to create a time series object. Only the data is required, not the dates or times associated with it...
A time series is said to be stationary when its statistical properties (such as mean and variance) do not change over the time at which the series is observed. Conversely, a time series is non-stationary when its statistical properties depend on time. For instance, time series with trends a...
Time-series datacomes from many sources today. A traditional relational database may not work well with time-series data because: Every data source requires a custom schema. This design means you must spend more time deciding how to store your data. Also, if there are changes in the underlyi...
Initiated by Tsinghua University, Apache IoTDB is an open-source project that serves as a platform to integrate IoT time-series data collection, storage, querying, and analysis. According to a benchmarking test conducted by the China Software Evaluation Center and Renmin University of China, IoTDB...
What is the difference between time series forecasting and regression analysis? The main difference between these two analysis types is that time series isextrapolationand regression isinterpolation. A time series forecasts takes previous data points and uses a mathematical model to predict future events...

The Hilbert-Huang transform (HHT) was developed late last century but has still to be introduced to the vast majority of economists. The HHT transform is a way of extracting the frequency mode features of cycles embedded in any time series using an adaptive data method that can be applied wi...

Time series analysis can be useful to see how a given asset, security, or economic variable changes over time. It also can be used to examine how the changes associated with the chosen data point compare to shifts in other variables over the same time period. Time series is also used in ...
