## How To Find Correlation Between Two Variables In R

#### r Interpreting correlations between two time-series

When using cross-correlations, I consider two things: 1. Is there an influence of one variable to the other, and if so, how much, and 2. What sort of lag do we have between the two variables w.r.t

That code is running a rolling correlation between the inter-period changes of the two series, i.e. looking at correlations of relative values rather than absolute values. Correlations of absolute values yield spurious results. Please see the links I noted, its all in there; if still not clear those links have some other links as well. Its crucial to understand this before looking any further

The Pearson correlation measures the linear relationship between two variables. Results range from -1 to +1 inclusive, where 1 denotes an exact positive linear relationship, as when a positive change in one variable implies a positive change of corresponding magnitude in the other, 0 denotes no linear relationship between the variance, and ?1 is an exact negative relationship.

#### r Interpreting correlations between two time-series

In the case of numerical variables, the standard association measure is the product-moment correlation coefficient introduced by Karl Pearson at the end of the nineteenth century, which provides a normalized measure of linear association between two variables. In building linear regression models, it is desirable to have high correlations - either positive or negative - between the prediction

If r=0, there is absolutely no relationship between the two variables. When r=0, on average, longer time spent on the exam does not result in any higher or lower grade. Most often r is somewhere in between -1.0 and +1.0.

Pokemon Go has run several events so far that have offered XP multipliers. During two of them, it was a blanket 2x multiplier for all XP — essentially a constant Lucky Egg — all day, every day, for the duration of the event. And yes, if you used a Lucky Egg at the same time, you got quadruple the XP.
