FYI @shoyer @fmaussion , I had to revisit the problem and ended up writing a function to compute vectorized cross-correlation, covariance, regression calculations (along with p-value and standard error) for xr.DataArrays. Essentially, I tried to mimic scipy.stats.linregress() but for multi-dimensional data, and included the ability to compute lagged relationships. Here's the function and its demonstration; please feel free to incorporate it in xarray if deemed useful: https://hrishichandanpurkar.blogspot.com/2017/09/vectorized-functions-for-correlation.html
