Next, suppose that I am interested in the number of mutations at 10 locations for 100 patients. I somehow know that the probability of mutation is the same at all the 10 locations. I have the following observation vector. X=c(0,0,0,0,0,0,0,0,0,1). Here X[ 1 ] is the number of patients with mutation at Position 1, X[ 2 ] is the same for Position 2, and so on. Using this observation vector, find an MLE of p. The MLE of p using the new observation vector is _____.
