can anyone help me to found the the likehood fonction for
Log-periodic-power-law ?

log(y(t))=A+(B(t-tc)^beta )(1+Ccos(wlog(tc-t)+phi)) A,B,C,beta,phi,tc,w
: are parameters to be estimeted.

i can't find an exemple to build analogie with this formula ..

i was working with Genetic algorithms, and when i ve decided to switch
to maximum likehood function i got problem to define the likehood
