nctinv
Noncentral t inverse cumulative distribution function
Syntax
X = nctinv(P,NU,DELTA)
Description
X = nctinv(P,NU,DELTA) returns
the inverse of the noncentral t cdf with NU degrees
of freedom and noncentrality parameter DELTA for
the corresponding probabilities in P. P, NU,
and DELTA can be vectors, matrices, or multidimensional
arrays that all have the same size, which is also the size of X.
A scalar input for P, NU, or DELTA is
expanded to a constant array with the same dimensions as the other
inputs.
Examples
x = nctinv([0.1 0.2],10,1) x = -0.2914 0.1618
