How do I calculate the maximum likelihood (machine learning statistics) of this table of data?
You might have mistaken the equation for maximum likelihood , and it should be like this :


  $p^y*(1-p)^{1-y}$


while y is your label , it should be 0 or 1 , 0 for negative and 1 for positive , and p is your sigmoid function value.

so , in your case it should be :


  p(2.5)*(1 - p(0.3))*p(2.8)*p(0.5)


Hopes this will help you , good luck !
