param,cp, coefficients, shape |
a numeric vector of parameter values. |
X |
a matrix of explanatory variables; must have col(X) equal to
length(y) . Missing values (NA ) are not allowed.
If X is missing, a one-column matrix of 1's is created.
|
x,y,z |
a numeric vector or matrix, depending on the context. |
freq |
a vector of frequencies. |
trace |
logical value which controls printing of the algorithm convergence.
If trace=TRUE , details are printed. Default value is FALSE .
|
free.param |
a vector of suitably re-parametrized parameters, not to be kept fixed during iteration. |
fixed.comp |
a vector containing the subset of the parameters for which the profile log-likelihood function is required; it can be of length 1 or 2. |
fixed.values |
a numeric vector of values or a matrix with two columns, giving the range spanned by the selected parameters. |
fixed.df |
a scalar value contaning the degrees of freedom (df), if these must
be taked as fixed, or NA (deafult value) if df is a parameter
to be estimated.
|
breaks |
a vector contaning the cut points of the groups, given
in ascending order. The last value can be Inf , the
first one can be -Inf
|
These functions are not intended to be called directly by the user.
A numeric value or a vector or a list.
