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
