how to permute lag-based variables #12

Closed thekingofkings closed 8 years ago

thekingofkings commented 8 years ago

So far I am permuting y as permuting social.lag, where social.lag = A * y. The A does not change.

However, calculating the A is not efficient. Therefore, a better solution is to directly permute social.lag, which calculate A only once.
