Usage
vb_cs_fpca(formula, data = NULL, verbose = TRUE, Kt = 5, Kp = 2,
alpha = 0.1, Aw = NULL, Bw = NULL, Apsi = NULL, Bpsi = NULL)
Arguments
formula
a formula indicating the structure of the proposed model.
data
an optional data frame, list or environment containing the
variables in the model. If not found in data, the variables are taken from
environment(formula), typically the environment from which the function is
called.
verbose
logical defaulting to TRUE -- should updates on progress be printed?
Kt
number of spline basis functions used to estimate coefficient functions
Kp
number of FPCA basis functions to be estimated
alpha
tuning parameter balancing second-derivative penalty and
zeroth-derivative penalty (alpha = 0 is all second-derivative penalty)
Aw
hyperparameter for inverse gamma controlling variance of spline terms
for population-level effects
Bw
hyperparameter for inverse gamma controlling variance of spline terms
for population-level effects
Apsi
hyperparameter for inverse gamma controlling variance of spline terms
for FPC effects
Bpsi
hyperparameter for inverse gamma controlling variance of spline terms
for FPC effects
