SpletI'm uncertain how I find/calculate the log likelihood function. I've understood the MLE as being taking the derivative with respect to m, setting the equation equal to zero and isolating m (like with most maximization problems). So finding the log likelihood function seems to be my problem ... If multiple sources are parallel with the diode ... Splet25. nov. 2024 · The log likelihood of your data is the sum of the log likelihood of each individual data point, all of which will be $\lt 0$.This means that unless your model is a very bad fit to the data, an extremely low log likelihood reflects the fact that you have an enormous number of data points.. Now, AIC is supposed to approximate out of sample …
