This function is a constructor for the corToep class,
representing a toeplitz correlation structure.
Objects created using this constructor must later be initialized
using the appropriate Initialize method.
Usage
corToep(value = numeric(0), form = ~1, fixed = FALSE)Arguments
- value
an optional vector of parameter values. Must have length number of levels - 1.
- form
a one sided formula of the form ~ t, or ~ t | g, specifying a time covariate and, optionally, a grouping factor g.
- fixed
an optional logical value indicating whether the coefficients should be allowed to vary in the optimization, or kept fixed at their initial value. Defaults to FALSE, in which case the coefficients are allowed to vary.
