Description Usage Arguments Value
The function returns either the penalized profile log-likelihood or the value that maximizes the penalized profile log-likelihood for a given tuning parameter value.
1 | pPPCA_INFO(lam, Tvotes = 100, M, AIC = TRUE, tau = 0.001, beta = NULL)
|
lam |
a numerical vector of positive sample eigenvalues |
Tvotes |
the number of possible tuning parameter values to be searched |
M |
the number of observations used to calculate sample covariance. |
AIC |
a logical indicator to use AIC as the information criterion, if FALSE, then BIC is used; the default option is AIC. |
tau |
a tolerance threshold for the smallest eigenvalue, the default value is 0.001. |
beta |
a numeric between 0 and 1 indicating the weight towards penalty function 1 or 2. |
an integer K that maximizes the penalized profile log-likelihood for the given delta
value.
