Analyzing climate data from 1850 to 2015 - A White Paper from XLSTAT

FACEBOOK.png

 

Introduction

The aim of this analysis is to describe, visualize and forecast temperature changes on a global scale. To do this, we use XLSTAT time series analysis. Analyzing temporal data is a specific branch of data and statistical analysis. This type of data is called time series data. We will present various methods that can be used to analyze this type of data.

The data used here are monthly air and ocean temperatures from 1850 to 2015.
