doublyT function

Approximation of the distribution function of the doubly noncentral t-distribution

Computes the value of the distribution function of the doubly noncentral t-distribution at x.

doublyT(x, df, lambda1, lambda2, lb = 0, ub)

Arguments

• x: a variable x.
• df: degrees of freedom (i.a. N-2).
• lb: lower bound for the starting value of the poisson distribution.
• ub: upper bound for the last value of the poisson distribution.

Returns

Distribution value of the doubly noncentral t-distribution at x.
