568378007 MDU6SXNzdWU1NjgzNzgwMDc= 3784 Function for regressing/correlating multiple fields? 56925856 closed 0     6 2020-02-20T15:24:14Z 2020-05-25T16:55:33Z 2020-05-25T16:55:33Z CONTRIBUTOR      

I came across this StackOverflow thread about applying linear regression across multi-dimensional arrays and there were some very efficient, xarray-based solutions suggested to the OP which leveraged vectorized operations. I was wondering if there was any interest in adding a function like this to future releases of xarray? It seems like a very neat and useful functionality to have, and not just for meteorological applications!
