This menu provides facilities for the analysis of one- or two-dimensional data
in the form of a grid using the method of residual maximum likelihood (REML),
which is also sometimes called restricted maximum likelihood. The data should
be supplied in a single variate with variate(s) to specify the Y positions
and X positions.
Data
Specifies a variate containing the data values.
Y Positions
A variate specifying the Y coordinates in the grid.
X Positions
A variate specifying the X positions in the grid. This is only required when
you have two-dimensional data.
Model
Lists the available correlation models. Select the correlation model that you
want to apply to the grid.
Distance Measure
Lists the distance measures that are available for the power correlation model.
Select the distance measure that you want to apply.
Form of Model
Allows the form of the model to be defined as either isotropic or anisotropic
Fixed Model
The fixed model describes imposed treatment factors and covariates for which
the effect of specified levels or values are of interest. The model is
described using a formula, which can combine main effects and interactions of
factors and also covariates.
Random Model
The random model is generally used to describe those factors for which the
values present in an experiment can be considered drawn from some large
homogeneous population. The model is described using a formula, which can
combine main effects and interactions of factors and also covariates.
Available Data
This lists data structures appropriate to the current input field. The
contents will change as you move from one field to the next. Double-click on a
name to copy it to the current input field; alternatively, you can type in the
name directly.
Operators
This provides a quick way of entering operators in the fixed and random model
formulas. Double-click on the required symbol to copy it to the current input
field. You can also type in operators directly. See Operators in model
formulae for a description of each.
