theta_j
We use @(@ \theta_j @)@ to denote one component of the fixed effects vector.

prior_id
We use prior_id for the prior that is attached to the j-th fixed effect; see prior for a variable .

lambda_j
If @(@ \theta_j @)@ is a smoothing standard deviation multiplier then @(@ \lambda_j = 1 @)@. Otherwise @(@ \lambda_j @)@ is the mulstd_value_prior_id multiplier for the smooth_id corresponding to @(@ \theta_j @)@.

mu_j
We use @(@ \mu_j @)@ to denote the mean corresponding to prior_id .

epsilon_j
We use @(@ \varepsilon_j @)@ to denote the std corresponding to prior_id .

eta_j
We use @(@ \eta_j @)@ to denote the eta corresponding to prior_id .

d_j
We use @(@ d_j @)@ to denote the density_id corresponding to prior_id . In an abuse of notation, we include eta and eta in d_j ; see d .

sigma_j
We use @(@ \sigma_j @)@ to denote the transformed standard deviation corresponding to prior_id @[@ \sigma_j = \left\{ \begin{array}{ll} \log ( \mu_j + \eta_j + \varepsilon_j ) - \log( \mu_j + \eta_j ) & \R{if \; log \; density} \\ \varepsilon_j & \R{otherwise} \end{array} \right. @]@

V_j^theta
The value density for the j-th component of @(@ \theta @)@ is @[@ V_j^\theta ( \theta ) = \exp \left[ D \left( \theta_j \W{,} \mu_j \W{,} \lambda_j \sigma_j \W{,} d_j \right) \right] @]@ where @(@ D @)@ is the log-density function .

V^theta
Let @(@ n @)@ be the number of fixed effects. The value density for all the fixed effects @(@ \theta @)@ is defined by @[@ V^\theta ( \theta ) = \prod_{j=0}^{n-1} V_j^\theta ( \theta ) @]@
