TimeStratPetersenDiagErrorWHSteel_fit {BTSPAS} | R Documentation |
Takes the number of marked fish released, the number of recaptures, and the number of unmarked fish and uses Bayesian methods to fit a fit a spline through the population numbers and a hierarchical model for the trap efficiencies over time. The output is written to files and an MCMC object is also created with samples from the posterior.

title |
A character string used for a title on reports and graphs |
prefix |
A character string used as the prefix for created files. All created graph files are of the form prefix-xxxxx.pdf. |
time |
A numeric vector of time used to label the strata. For example, this could be julian week for data stratified at a weekly level. |
n1 |
A numeric vector of the number of marked fish released in each time stratum. |
m2 |
A numeric vector of the number of marked fish from n1 that are
recaptured in each time stratum. All recaptures take place within the
stratum of release. Use the |
u2.W.YoY |
A numeric vector of the number of unmarked wild Young-of-Year fish captured in each stratum. |
u2.W.1 |
A numeric vector of the number of unmarked wild age 1+ fish captured in each stratum. |
u2.H.1 |
A numeric vector of the number of unmarked hatchery age 1+ fish (i.e. adipose fin clipped) captured in each stratum. |
sampfrac |
Deprecated because it really doesn't work as intended. You must remove all references to sampfrac from your code. Contact cschwarz.stat.sfu.ca@gmail.com for more information. |
hatch.after |
A numeric vector with elements belonging to |
bad.n1 |
A numeric vector with elements belonging to |
bad.m2 |
A numeric vector with elements belonging to |
bad.u2.W.YoY |
A numeric vector with elements belonging to |
bad.u2.W.1 |
A numeric vector with elements belonging to |
bad.u2.H.1 |
A numeric vector with elements belonging to |
logitP.cov |
A numeric matrix for covariates to fit the logit(catchability). Default is a single intercept, i.e. all strata have the same mean logit(catchability). |
n.chains |
Number of parallel MCMC chains to fit. |
n.iter |
Total number of MCMC iterations in each chain. |
n.burnin |
Number of burn-in iterations. |
n.sims |
Number of simulated values to keeps for posterior distribution. |
tauU.alpha |
One of the parameters along with |
tauU.beta |
One of the parameters along with |
taueU.alpha |
One of the parameters along with |
taueU.beta |
One of the parameters along with |
prior.beta.logitP.mean |
Mean of the prior normal distribution for logit(catchability) across strata |
prior.beta.logitP.sd |
SD of the prior normal distribution for logit(catchability) across strata |
tauP.alpha |
One of the parameters for the prior for the variance in logit(catchability) among strata |
tauP.beta |
One of the parameters for the prior for the variance in logit(catchability) among strata |
run.prob |
Numeric vector indicating percentiles of run timing should be computed. |
debug |
Logical flag indicating if a debugging run should be made. In the debugging run, the number of samples in the posterior is reduced considerably for a quick turn around. |
debug2 |
Logical flag indicated if additional debugging information is
produced. Normally the functions will halt at |
InitialSeed |
Numeric value used to initialize the random numbers used in the MCMC iterations. |
save.output.to.files |
Should the plots and text output be save to the files in addition to being stored in the MCMC object? |
Normally, data is passed to the wrapper which then calls the fitting function.
An MCMC object with samples from the posterior distribution. A series of graphs and text file are also created in the working directory.
