- To use
, you first need to load the Linear Regression Package using 
. - The i
row of a design matrix contains the values of the basis functions funs evaluated at the values for the i
element in data. - The data can have the form
, where the number of coordinates 
is equal to the number of variables in the list vars. - The data can also be of the form
, with a single coordinate assumed to take values 
. - The argument funs can be any list of functions that depend only on the variables vars.
- The following option can be given:
-
IncludeConstant True whether to automatically include a constant as one of the functions - With the default setting IncludeConstant->True, the constant
is included as the first entry in the list of basis functions if a constant is not included in funs.
