Calculate the estimated projection matrices for every kernels in the kernel library.
1 | estimate_base(Y, X, K_list, mode, lambda, ...)
|
Y |
(matrix, n*1) The vector of response variable. |
X |
(matrix, n*d_fix) The fixed effect matrix. |
K_list |
(list of matrices) A nested list of kernel term matrices. The first level corresponds to each base kernel function in kern_func_list, the second level corresponds to each kernel term specified in the formula. |
mode |
(character) A character string indicating which tuning parameter criteria is to be used. |
lambda |
(numeric) A numeric string specifying the range of tuning parameter to be chosen. The lower limit of lambda must be above 0. |
... |
Additional parameters to pass to estimate_ridge. |
For a given mode, this function returns a list of projection matrices for every kernel in the kernel library and a n*K matrix indicating errors.
A_hat |
(list of length K) A list of projection matrices for each kernel in the kernel library. |
P_K_hat |
(list of length K) A list of projection matrices to kernel space for each kernel in the kernel library. |
beta_list |
(list of length K) A list of fixed effect estimators for each kernel in the kernel library. |
alpha_list |
(list of length K) A list of kernel effect estimates for each kernel in the kernel library. |
kern_term_list |
(list of length K) A list of kernel effects for each kernel in the kernel library. |
A_proc_list |
(list of length K) A list of projection matrices for each kernel in the kernel library. |
lambda_list |
(list of length K) A list of selected tuning parameters for each kernel in the kernel library. |
