Assume that you have datapoints $(x_i,y_i)$ that have an exponential relationship: $(x_i,\log(y_i))$ approximate a straight line. This means that the stochasticstatistical variables $X$ and $\log(Y)$ are positively correlated. But what can you say about $X$ and $Y$ in this case?

What is the correlation of two variables that have an exponential relationship?
