In this case, it is possible excel visual basic open file can be easily reparametrized as where is our new parameter and there are no constraints on it, because it can

Coding the log-likelihood function The likelihood function is coded as a routine that takes as inputs a value for the parameter and the data, and returns as output the value of the log-likelihood with ifle sign changed. The code is as follows. It takes as arguments the parameter theta and the vector of observations data. In particular, tpdf(data,n) returns a vector of densities (one density for each observation in the vector data ), fike the hypothesis that the number of degrees of freedom is equal to n. By taking the natural logarithm with the log function and summing over all entries of the vector, we obtain fiile log-likelihood of the sample. In other words, with the command sum(log(tpdf(data,df))) we compute the log-likelihood where is an observation (a component of the vector data ), is the visuall size (the dimension of the vector data ) and is the probability density function of.
