Usage

gadget_surveydistribution_component(
  weight = 0,
  name = "surveydistribution",
  data = NULL,
  area = NULL,
  length = NULL,
  age = NULL,
  stocknames = c(),
  fittype = "linearfit",
  parameters = NULL,
  suitability = list(),
  slope = NULL,
  intercept = NULL,
  epsilon = 10,
  likelihoodtype = "multinomial"
)

Arguments

weight	A numeric weighting
name	A descriptive name for the component, default same as component type
data	data.frame of age-length survey indices that Gadget is to use to fit the likelihood function to
area	Area aggregation, if not attached to the data.frame by MFDB
length	Length aggregation, if not attached to the data.frame by MFDB
age	Age aggregation, if not attached to the data.frame by MFDB
stocknames	A list of all the stocks to be aggregated into a single pseudo stock
fittype	Type of linear regression to use. One of 'linearfit' / 'powerfit'
parameters	Vector of 2 parameters that are used to calculate the survey index values from the modelled population
suitability	Suitability function for survey fleet
slope	Parameter for linear regression
intercept	Parameter for linear regression
epsilon	Used when probability is very unikely, default 10.
likelihoodtype	What function is to be used to compare the modelled survey index distribution to the input survey index distribution. One of 'multinomial' / 'pearson' / 'gamma' / 'log'
