Fitting multinomial models to synthetic data
Fits multinomial models to the synthesised data set(s)
using the multinom function.
multinom.synds(formula, data, ...)
formula |
a symbolic description of the model to be estimated.
A typical model has the form |
data |
an object of class |
... |
additional parameters passed to |
To print the results the print function (print.fit.synds) can be used.
The summary function (summary.fit.synds) can be used
to obtain the combined results of models fitted to each of the m synthetic
data sets.
An object of class fit.synds. It is a list with the following
components:
call |
the original call to |
mcoefavg |
combined (average) coefficient estimates. |
mvaravg |
combined (average) variance estimates of |
analyses |
an object summarising the fit to each synthetic data set
or a list of |
fitting.function |
function used to fit the model. |
n |
a number of cases in the original data. |
k |
a number of cases in the synthesised data. |
proper |
a logical value indicating whether synthetic data were generated using proper synthesis. |
m |
the number of synthetic versions of the observed data. |
method |
a vector of synthesising methods applied to each variable in the saved synthesised data. |
incomplete |
a logical value indicating whether any of the variables in the model were not synthesised. |
mcoef |
a matrix of coefficients estimates from all |
mvar |
a matrix of variance estimates from all |
