doublyF_opt function

Distribution function of the non central F-distribution

doublyF_opt(x, df1, df2, lambda1, lambda2, acc = 100, ex = 5)

Arguments

• x: quantile, a single numeric value
• df1: first degree of freedom, a single integer value
• df2: second degree of freedom, a single integer value
• lambda1: first non centrality parameter, a single numeric value
• lambda2: second non centrality parameter, a single numeric value
• acc: accuracy; last index of the approximation of the infinite sum
• ex: exactness; break early, if the summands are smaller than 10^(-ex)

Returns

Probability of observing a value larger than x
