Re: Missing values in LOGL series under Bi-variate GARCH
Hi, i´m facing a similar problem like the guys above. Im trying to do a dcc garch to examine the correlation of stock markets from 2000 to 2018. I used my code for another study before without any problems, but this time i always get an "Missing valuesin @LOGL series at current coefficients at ...
