Gibbs_AS_posteriorCPP | R Documentation |
Use a Gibbs sampler for the A and S variables (E-step of the EM)
Gibbs_AS_posteriorCPP( nsamp, nburn, template_mean, template_var, S, G, tau_v, Y, alpha, final, return_samp )
nsamp |
the number of posterior samples to output after burn-in |
nburn |
the number of posterior samples to throw away before saving |
template_mean |
a matrix with dimensions V x Q giving the mean value of the independent components |
template_var |
a matrix with dimensions V x Q giving the variance of the independent components |
S |
a matrix with dimensions V x Q of subject independent components |
G |
a Q x Q matrix of the prior covariance of A |
tau_v |
a length V vector with noise variance for each data location |
Y |
a matrix with dimensions V x T of observed BOLD data |
alpha |
a length Q vector of the prior mean of all rows of A |
final |
a boolean. Should posterior samples be returned instead of summary measures? |
return_samp |
a boolean. Should posterior samples be returned? |
List with estimates for A, S, and possibly other quantities
