orglsSet {goric} | R Documentation |
Set of generalised least-squares models
Description
Fitting a specific set of generalisd least-squares models with order restrictions.
Usage
orglsSet(formula, data, weights = NULL, correlation = NULL, set,
direction = "increase", n = NULL, base = 1, control = orlmcontrol())
Arguments
formula |
an object of class "formula" (or one that can be coerced to that class): a symbolic description of the model to be fitted. |
data |
an optional data frame, list or environment (or object coercible by as.data.frame to a data frame) containing the variables in the model. If not found in data, the variables are taken from environment(formula), typically the environment from which lm is called. |
weights |
a |
correlation |
a |
set |
either a character string (see |
direction |
direction of the order constraints |
n |
a (possibly named) vector of sample sizes for each group |
base |
column of the constraint matrix representing a control group |
control |
a list of control arguments; see |
Details
This function is just a wrapper for repeated calls of orgls
with different constraint definitions. Predefined lists with constraint-sets can be constructed with function constrSet
.
Value
a list with orgls objects
