HQ realized that rank=2 for two variable is actually a good combination.
Moderate cointegration of Rt and Apple driving.
Northern states are more likely to have Rt ~ T2m
Confirmed by Rt, T2m, Apple-driving
21:30. HQ added adf.test and found many small p-value for T2m, dewpoint and even Rt. Small p-value of ADF-test means alternative hypothesis cannot be rejected. This means dewpoint are mostly stationary.

Augmented Dickey-Fuller Test
data: x_nona[, 1]
Dickey-Fuller = -5.2384, Lag order = 5, p-value = 0.01
alternative hypothesis: stationary
