Internal function. Given the probability distribution of independent test statistics T1 and T2, the function finds the joint distribution of T1, T1+T2.
jointcrit(p1, p2, alpha = 0.05)
The probability distribution of the test statistic T1 taking on values 0, 1, 2,..., maximum value
The probability disribution of the test statistic T2 taking on values 0, 1, 2, ..., maximum value
The significance level at which the test is conducted.
Matrix which contains for each possible value of t1 and t2, information about the probability of T1>=t1, T1+T2>=t1+t2.
