## What is spurious correlation?

Spurious correlation, or spuriousness, occurs when two factors appear casually related to one another but are not. The appearance of a causal relationship is often due to similar movement on a chart that turns out to be coincidental or caused by a third “confounding” factor.

How do you deal with spurious correlation?

Correlation is not causation. Spurious correlation is especially likely to occur with time series data, where two variables trend upward over time because of increases in population, income, prices, or other factors. The simplest remedy is to work with changes or percentage changes.

### What is a spurious correlation and how is it different from mistaking correlation for causation?

A spurious correlation in statistics represents a connection between two variables that seems to be a causal relationship but really is not. A causal relationship describes a cause-and-effect relationship between two variables where one variable does something that directly affects the other.

#### What causes spurious regression?

Spurious regression happens when there are similar local trends. The solid line is y and dotted line is x. Sometimes their local trends are similar, giving rise to the spurious regression. In short, two series are cointegrated if they are nonstationary and related.

What causes a spurious correlation quizlet?

Why does spurious regression occur?

We show that spurious regression can be traced to three sources: the presence of a linear trend, the presence of high autocorrelation, and the presence of breaking trends. In the first case, the spurious regression problem arises from the omission of trend functions in the regression model.
