Shrinkage {assist} | R Documentation |
Return a matrix evaluating reproducing kernels for the discrete shrinkage towards zero or the mean estimate
shrink0(x, y=x)
shrink1(x, y=x)
x |
a vector of numerical values or factor indicating different levels. |
y |
a vector of numerical values or factor indicating different levels. Default is x. |
a matrix with the numbers of row and column equal to the length of x and y respectively.
The [i, j]
element is the reproducing kernel evaluated at the ith element of x and jth element of y.
shink0
shrinks towards zero, and shrink1
shinks towards the mean.
