Arguments

obj

a model object, e.g. of class lm or glm

alpha

level of the confidence intervals; their coverage should be 1-alpha/2

...

further arguments; ignored.

Value

Any method of getSummary must return a list with the following components:

coef

an array with coefficient estimates; the lowest dimension must have the following names and meanings:

est

the coefficient estimates,

se

the estimated standard errors,

stat

t- or Wald-z statistics,

p

significance levels of the statistics,

lwr

lower confidence limits,

upr

upper confidence limits.

The higher dimensions of the array correspond to the individual coefficients and, in multi-equation models, to the model equations.

sumstat

a vector containing the model summary statistics; the components may have arbitrary names.

Details

The generic function getSummary is called by mtable in order to obtain the coefficients and summaries of model objects. In order to adapt mtable to models of classes other than lm or glm one needs to define getSummary methods for these classes and to set a summary template via setSummaryTemplate
