This help file describes how to input factor details for general designs
Select
(and also by clicking on an item in the listboxes below the frame).
Repeatedly jumping through the frame with the Tab
key automatically
cycles through the factors one by one.
The number of levels MUST BE ENTERED for each factor. (Jumping out of the entry box without entering a valid number of levels creates an error message popup.) The levels themselves are then automatically set to the integer numbers from one to the number of levels. Different levels (separated by blanks) can be manually entered. It is recommended to use the automatic levels for preliminary checks on available designs and their properties, but to enter meaningful factor levels for experiments that will actually be run.
The entry Comment or label
is included into an exported html file as
annotation for the factor. This may be useful for conducting the experiment.
Move Up
and
Move Down
can be used for changing the order of the factors.
Specifying column numbers can be useful, if an expert user has investigated the
properties of a design and wants to obtain a better-suited design than the
default one. For example, when accomodating two 2-level factors, one 4-level factor
and one 8-level factor in L64.2.5.4.10.8.4
, it is better to use columns 2 and 3
than the default columns 1 and 2 for the two 2-level factors.
