Hi

The probabilities of sets of twins are as follows.

Both Male: 1/4(1+theta)

Both Female: 1/4(1+theta)

Mixed Sex: 1/2(1-theta)

From a study of 200 pairs if twins:

Both Male= 78

Both Female= 59

Mixed= 63

Find the Likelihood and Maximum Likelikodd estimator for the data.

I've never dealt find findng likelihoods of datas, just of functions.

Can anyone help?!
