A key part of getting valid approximations to a spatial field in INLA is forming a "good" mesh (triangulation). This section of the "SPDE Tutorial" on the INLA website describes...

HW 4 low Linf estimates & converging half the time

1

My model including the spatial trend runs but returns too low of estimates of Linf (mostly ranging in 30-40). I am not sure why it would be consistently be estimating...

Lab 5 logit transformation on rho

1

In lab 5, logit_rho is entered as a parameter, but it is later logit inverse-transformed into rho (in the objective function section), where rho is used later in the script...

Extracting standard error in R for estimated time series

7

I am having trouble getting std. error out of the TMB code. I am using ADREPORT(log_x_t); for the estimated time series, but can't seem to access std. error for it...

Estimating biomass (HW 3)

1

I am trying to figure out how to estimate biomass for all 36 years while only fitting the first 31 years. I have the two 'jnll' statements, 1. estimates the...

Optimizer Error for random = NA

1

I noticed setting random = NA (for the first model) results in the error (only when trying to optimize): TMB as received an error from Eigen. index>=0 && index <...
