In statistics, a spurious correlation (also known as spuriousness) refers to a connection between two variables that appears to be causal but is not. With spurious correlation, any observed dependencies between variables are merely due to chance or are both related to some unseen confounding factor...

Spurious Correlations can appear in the form of non-zero correlationcoefficientsand as patterns in a graph. For instance, in the following example fromtylervigen.com, the correlation between U.S. crude oil imports from Norway and drivers killed in a collision with a railway train has a very ...

The DAC3482 output is being fed to an RF Modulator and up-converted in the graph data provided. 180MHz IF frequency (sinusoidal) output from DAC3482, up-converted to 5.75GHz. The only thing changing between a good and bad output is the toggling of the SIF ...
1.4. Concept of Eco-Geographical Zoning to Aid in Spurious Change Detection Land cover is an element relating to resources and the environment and depends on the geographical environment of a specific region. The geographical environment comprises regional differentiation and spatial correlations. The di...
So.., analysis of two Random Walks which are clearly independent from each otherby construction, and the analysis of two time series in levels can have same qualitative result, as if there is a significant positive correlation, that can’t be good right?
Spurious Regression problem dates back to Yule (1926): “Why Do We Sometimes Get Nonsense Correlations between Time-series?”. Lets see what is the problem, and how can we fix it. I am using Morgan Stanley (MS) symbol for illustration, pre-crisis time span. Take a look at the followin...
Such method also finds applications in exploring the underlying network evolutionary mechanisms. Link prediction algorithms aim at estimating the tendency of the existence of a link between two nodes, based on observed links, attributes of nodes, or dynamical correlations1–3. As our knowledge on ...
