dirmult.summary {dirmult}

Summary table of parameter estimates from dirmult

Description

Produces a summary table based on the estimated parameters from dirmult. The table contains MLE estimates and standard errors together with method of moment (MoM) estimates and standard errors based on MoM estimates from 'Weir and Hill (2002)'.

Usage

dirmult.summary(data, fit, expectedFIM=FALSE)

Arguments

data

A matrix or table with counts. Rows represent subpopulations and columns the different categories of the data. Zero rows or columns are automaticly removed.

fit

Output from dirmult used on the same data table as above.

expectedFIM

Logical. Determines whether the observed or expected Fisher Information Matrix should be used. For speed use observed (i.e. FALSE) - for accuracy (and theoretical support) use expected (i.e. TRUE).

Value

Summary table with estimates and standard errors for \pi and \theta.
