loglik_kappa_est {templateICAr} | R Documentation |
Kappa log-likelihood
Description
Applicable to a single latent field, or multiple latent fields if common smoothness is assumed
Usage
loglik_kappa_est(par, delta, D_diag, mesh, C1 = 1/(4 * pi), Q = NULL)
Arguments
par |
Vector of length two containing values of log kappa and log residual variance at which to compute log likelihood |
delta |
Estimate of delta (subject effect or deviation) |
D_diag |
Diagonal values of D matrix (template standard deviations) |
mesh |
Object of class "templateICA_mesh" containing the triangular mesh (see |
C1 |
For the unit variance case, |
Q |
Equal to the number of ICs for the common smoothness model, or NULL for the IC-specific smoothness model |
Details
Compute log-likelihood of kappa given an initial estimate of delta
Value
Value of negative log likelihood
