A dataset containing information necessary to run an age-structured stock
assessment model in FIMS for milestone 1. This data was generated using
the ASSAMC package written for the model comparison project.
Format
A data frame with 1140 observations of 8 variables:
- type
The type of data the row contains. Allowed types include
age,index,landings, andweight-at-agedata.- name
A character string providing the name of the information source that the data was collected from, e.g.,
"Trawl fishery"- age
An integer age. Entry can be
NAif information pertains to multiple ages, e.g., total catch rather than catch of age-4 fish.- datestart,dateend
Start and end dates of the data collection period. Format all dates using
yyyy-mm-dd, which can accommodate fake years such as0001-01-01.- value
The measurement of interest.
- unit
A character string specifying the units of
value. Allowed units for each data type are as follows.mtis used forindex,landings, andweight-at-agedata.numberorproportionare each viable units for the composition data, where the former is the preferred unit of measurement.- uncertainty
A real value providing a measurement of uncertainty for value. For catches and survey indices of abundance this should be the standard deviation of the logged observations if you are using the lognormal distribution to fit your data. For composition data it will be your input sample size.
