Comment/Request

why is lngamma(x) different from ln(gamma(x))?
e.g. lngamma(-2.1) = 1.53171 -9.42478i and ln(gamma(-2.1) = 1.53171 +3.14159i
And even more curious: lngamma(-1.1) = 2.27365 -6.28319i and ln(gamma(-1.1)) = 2.27365

What's the accuracy given the true labels t and the predicted labels p

t = (1,3,2,4,3,2,1,4,3,2,3,4)

p = (1,2,2,4,4,2,1,4,1,2,3,4)
