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
