nctinv

Inverse of the noncentral T cumulative distribution

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. Vector or matrix inputs for P, NU, and DELTA must have the same size, which is also the size of X. A scalar input for P, NU, or DELTA is expanded to a constant matrix with the same dimensions as the other inputs.

Example

• x = nctinv([0.1 0.2],10,1)
  x =
     -0.2914    0.1618
