ENSO-region SSTs Causality On US Precipitation

New

Can we prove causality between ENSO-region SSTs and U.S. Precipitation?

Following X. San Liang "Unraveling the cause-effect relation between time series" Phys. Rev. E, 90, 052150 (2014)
Note this is a maximum likelihood estimate (MLE) of the information flow under the assumption of a linear model with additive noise.
