Multinomial logistic regression values
returns
the predicted probabilities for the multinomial logistic regression
model with predictors, pihat
= mnrval(B
,X
)X
, and the coefficient estimates, B
.
pihat
is an nbyk matrix
of predicted probabilities for each multinomial category. B
is
the vector or matrix that contains the coefficient estimates returned
by mnrfit
. And X
is
an nbyp matrix which contains n observations
for p predictors.
Note:

)pihat
,
using the statistics in the structure, stats
, returned
by mnrfit
.
The lower and upper confidence bounds for pihat
are pihat
minus dlow
and pihat
plus dhi
,
respectively. Confidence bounds are nonsimultaneous and only apply
to the fitted curve, not to new observations.
