distfun_nctinv

Noncentral T Inverse CDF

Calling Sequence

x = distfun_nctinv ( p , v , delta )
x = distfun_nctinv ( p , v , delta , lowertail )

Parameters

p :

a matrix of doubles, the probability. Must be in the range [0,1].

v :

a matrix of doubles, the number of degrees of freedom, v>0.

delta :

a matrix of doubles, the noncentrality parameter, delta is real

lowertail :

a 1-by-1 matrix of booleans, the tail (default lowertail=%t). If lowertail is true (the default), then considers P(X<=x) otherwise P(X>x).

x :

a matrix of doubles, the outcome

Description

Computes the Inverse Noncentral T cumulative probability distribution function.

Any scalar input argument is expanded to a matrix of doubles of the same size as the other input arguments.

Caution This distribution is known to have inferior accuracy in some cases.

Examples

x = distfun_nctinv(0.7,5,10)
expected=8.9885923
