SS_fitbiasramp: Estimate bias adjustment for recruitment deviates
In r4ss: R code for Stock Synthesis

Description Usage Arguments Author(s) References See Also

Uses standard error of estimated recruitment deviates to estimate the 5 controls for the bias adjustment in Stock Synthesis

SS_fitbiasramp(replist, verbose=FALSE, startvalues=NULL, method="BFGS",
  twoplots=TRUE, transform=FALSE, plot=TRUE, print=FALSE,
  plotdir="default", oldctl=NULL,
  newctl=NULL, nlminb=TRUE, pwidth=7, pheight=7, punits="in",
  ptsize=12, res=300, cex.main=1)

`replist`	Object created using `SS_output`
`verbose`	Controls the amount of output to the screen. Default=FALSE.
`startvalues`	A vector of 5 values for the starting points in the minimization. Default=NULL.
`method`	A method to apply to the 'optim' function. See ?optim for options. Default="BFGS".
`twoplots`	Make a two-panel plot showing devs as well as transformed uncertainty, or just the second panel in the set? Default=TRUE.
`transform`	An experimental option to treat the transform the 5 quantities to improve minimization. Doesn't work well. Default=FALSE.
`plot`	Plot to active plot device?
`print`	Print to PNG files?
`plotdir`	Directory where PNG files will be written. By default it will be the directory where the model was run.
`oldctl`	Optional name of existing control file to modify. Default=NULL.
`newctl`	Optional name of new control file to create from old file with estimated bias adjustment values. Default=NULL.
`nlminb`	Use the 'nlminb' function instead of 'optim'? Default=TRUE
`pwidth`	Default width of plots printed to files in units of `punits`. Default=7.
`pheight`	Default height width of plots printed to files in units of `punits`. Default=7.
`punits`	Units for `pwidth` and `pheight`. Can be "px" (pixels), "in" (inches), "cm" or "mm". Default="in".
`ptsize`	Point size for plotted text in plots printed to files (see help("png") in R for details). Default=12.
`res`	Resolution of plots printed to files. Default=300.
`cex.main`	Character expansion for plot titles.
