R Documentation

Creation of a design matrix object

The function takes design/model information as input and performs initial computations for prediction and testing.

x_Obj(D, model)

`D`	A list containing a regressor matrix for each model term
`model`	The model coded as a matrix

See the source code of ffmanova to see how D and model are created.

`df_error`	degrees of freedom for error
`D`	same as input
`D_test`	as `D`, but with Type II* adjusted model terms. Will be used for testing.
`D_om`	as `D`, but with OM-adjusted model terms. This is a non-overparameterised representation of the model. Will be used for prediction.
`df_D_om`	degrees of freedom according to `D_om`
`df_D_test`	degrees of freedom according to `D_test`
`Beta_D`	output from `linregEst` where `D_om` is response and where `D` is regressor
`VmodelDivS_D`	as above
`VextraDivS1_D`	as above
`Umodel`	output from `linregStart` where `D_om` is regressor
`VmodelDivS`	as above
`VextraDivS1`	as above
`termNames`	model term names
