Description
Methods for probit models
Usage
## S3 method for class 'probit'
fitted(object, ... )
## S3 method for class 'probit'
logLik(object, ... )
## S3 method for class 'probit'
nobs(object, ... )
## S3 method for class 'probit'
nObs(x, ... )
## S3 method for class 'probit'
print( x, digits = max(3, getOption("digits") - 3), ... )
Arguments
object , x |
object of class |
digits |
the minimum number of significant digits of the coefficients to be printed. |
... |
further arguments (currently ignored). |
Details
The fitted
method returns a vector of fitted values (probabilities).
The logLik
method returns the log likelihood value of the model.
The nobs
and nObs
methods return the number of observations.
The print
method prints the call and the estimated coefficients.
Furthermore, some standard methods can be applied to probit models:
the coef
method returns the vector
of the estimated parameters.
The df.residual
method returns the degrees of freedom
of the residuals.
The lrtest
method can be used to perform
likelihood-ratio tests.
The stdEr
method returns the vector
of the standard errors of the estimated parameters.
The vcov
method returns the variance covariance matrix
of the estimated coefficients.
The methods linearPredictors.probit
,
model.frame.binaryChoice
,
model.matrix.binaryChoice
,
residuals.probit
, and summary.probit
are described at seperate help pages.
