Description
A repackaged diabetes dataset [Hastie and Efron (2012)] is a list of two different design matrices
and a response vector with 442 observations [Efron et. al. (2004)]
The x matrix has been standardized to have unit L2 norm in each
column and zero mean. The matrix x2 consists of x plus 54 interaction terms.
Usage
1
Format
A list of 3 data objects,
x: A data frame with 10 variables and 442 observations
y: a numeric response vector of 442 observations
x2: a design matrix including interaction terms with 64 columns and 442 observations.
