Extracting characteristics from time series data

Click For Summary

Discussion Overview

The discussion revolves around extracting characteristics from time series data, focusing on statistical analysis and forecasting behaviors based on observed metrics. Participants explore various methods and models applicable to time series analysis.

Discussion Character

  • Exploratory
  • Technical explanation
  • Mathematical reasoning

Main Points Raised

  • One participant seeks to identify and measure various characteristics from a random set of time series data, mentioning specific metrics like trend linearity, peak sizes, and duration of values above or below certain thresholds.
  • Another participant suggests using Fourier transform and Artificial Intelligence as potential methods for forecasting behaviors in the time series data.
  • A different participant introduces the Auto Regressive Integrated Moving Average (ARIMA) model, highlighting its focus on dependencies between current and prior values and referencing the Box-Jenkins technique for modeling ARIMA processes.
  • A later reply expresses gratitude for the suggestions and notes that the ARIMA technique has been particularly effective for their analysis.

Areas of Agreement / Disagreement

Participants generally agree on the usefulness of the techniques discussed, particularly ARIMA, but there is no consensus on a comprehensive list of characteristics to extract from the time series data.

Contextual Notes

The discussion does not resolve the limitations regarding the completeness of the list of characteristics or the specific conditions under which different methods may be most effective.

hi

I have a random set of time series data that is calculated after applying an algorithm to a main random time serie data, and really need to extract all the possible characteristics from the set. The goal is to measure those characteristics and perform some statistical graphs based on those measurements ad try to forecast what are the possible next behaviours of the main set.

At the moment I have observed the next characteristics:
  1. Trend linearity and curvature
  2. Size of peak and trough
  3. Time that the value is over 80 or under 20
  4. etc...
I think there are much more characteristics that can be observed. The problem is I cannot find a list with characteristics.

Thank you very much guys, I have tried the techniques you mentioned and it worked very good, specially the ARIMA.
