I'm performing some panel regressions with time dummy
variables. In the results i see the Wald test. How do i interpret its results??
Test di Wald per la significativitą congiunta delle
dummy temporali
Statistica test asintotica: Chi-quadro(3) =
75,8035
con p-value = 2,43713e-016
Another question: my indipendent variable is the
sensibility of the Black and Scholes value of stock options to the volatility of
stock returns (VEGA). Should i use the log of Vega? Why?
Thanks very much
