Petrale STAR Day 1 Requests

Petrale STAR Day 1 Requests. 1. plot random vessel-year effects versus year for NWFSC survey. Presence-Absence. Positive. 2. Compare NWFSC indices and error bars when year-strata effects are random or fixed. Model 1 – Strata:Year Fixed Model 2 – Strata:Year Random.

  1. Petrale STAR Day 1 Requests

  2. 1. plot random vessel-year effects versus year for NWFSC survey Presence-Absence Positive

  3. 2. Compare NWFSC indices and error bars when year-strata effects are random or fixed Model 1 – Strata:Year Fixed Model 2 – Strata:Year Random

  4. 3. Report what depth selection was used for fishery CPUE. • Depth selection was: Depth ≤ 75 fathoms (for Summer) 150 fathoms ≤ Depth ≤ 400 fathoms (for Winter)

  5. 4. Look at vonB residuals by year.

  6. 4. Look at vonB residuals by year.

  7. 5. Set the NWFSC extra variance parameter to zero. • Base_old (Estimate extra SD for NWFSC) • Base (Extra SD for NWFSC=0)

  8. 6. Provide a time-series plot of discarded catch by fleet.

  9. 7. Check for convergence the sensitivity run removes NWFSC 2012 age composition data. • Run in draft document removed ALL NWFSC survey age data • New run removes only 2012 NWFSC survey age data

  10. 8. Report statistics on jitter analyses. • Jitter of 0.01 run for base case, 100 times • 75% ended at base case • 17.5% ended at local minima • 7.5% crashed

  11. 9. Provide M and h sensitivity analyses, based on range from hessian-based intervals.

  12. 9. Provide M and h sensitivity analyses, based on range from hessian-based intervals. • low h = 0.78; high h= 0.91

  13. 9. Provide M and h sensitivity analyses, based on range from hessian-based intervals. • low M = 0.14; high M= 0.18

  14. 10. Provide a sensitivity run with no commercial CPUE

  15. 10. Provide a sensitivity run with no commercial CPUE

  16. Comparison of all model runs for Day 1 STAR Requests

  17. 11. If time permits, provide an explanation of what component(s) produced the increase in the total likelihood profile for Ro.

  18. 11. If time permits, provide an explanation of what component(s) produced the increase in the total likelihood profile for Ro.
