WebIn practice, R will report the value of the log likelihood of the data; that is, the logarithm of the probability of the observed data coming from the estimated model. For given values of \ ... {AIC} + [\log(T)-2](p+q+k+1). \] Good models are obtained by minimising the AIC, AICc or BIC. Our preference is to use the AICc. WebOct 22, 2013 · At the end of the body of that function, there are some sub-functions starting with "negloglike" like 'negloglike_clayton'. By using those functions out of 'copulafit', you can have negative likelihood values for different copula families. having this value, you can easily calculate AIC or BIC (maybe using 'aicbic' function). on 10 Sep 2024.
