ln(V/D)=...

1. I try to think them as comparing (V-D)/V with the multiple of sigma_a, does it right?
2. Also, how can we connect it to the one given in the chapter of DeServigny...
Hello David:
the formula about the long term mean volatility of GARCH(1,1)(p.18 of 2008 formula) is a little wrong...

GARCH (1, 1) is unstable if the persistence > 1. A persistence of 1.0 indicates no mean reversion.
A low persistence (e.g., 0.6) indicates rapid decay and high...
