In Example 13.4.3, suppose that q is the probability that a child is a female. Obtain an EM sequence for = (p, q). Example

In Example 13.4.3, suppose that q is the probability that a child is a female. Obtain an EM sequence for θ = (p, q).
Example 13.4.3
Suppose that in a set of n twin pairs of children, n1 are male twin pairs, n2 are female twin pairs, and n3 = n – (n1 + n2) are opposite-sex twin pairs. Let p be the probability that a twin pair is identical and q be the probability that a child is male. It is not known which pairs of same-sex twins are identical. Obtain an EM sequence for θ = (p, q).
