data frame of estimated trends (wild and total spawners)

This returns a data frame that is written to a csv file. Not exported. It is used by inst/doc/report_files/esu_report.Rmd.

It returns the smoothed total spawners estimate and the smoothed wild spawners estimate which is "smoothed total estimate x smoothed fracwild estimate". The wild spawner estimate is only shown from 1 year before and one year after the last actual fracwild estimate (in the data file). This is done so that the wild estimate does not over-extend the fracwild data. Fracwild estimates can be interpolated for missing years, but would not be appropriate to extend much before or past actual observed (or expert) fracwild data.

For the smoothed total estimates, information from all populations (via a non-diagonal year-to-year variance matrix) is used to estimate missing values and to account for observation error in the total spawner count. Because data from all populations are used, estimates can be made even for missing years at the beginning of the time series if there is data for those early years in other populations.
