Define Age Error Matrix

Source: R/StoxBaselineFunctions.R
DefineAgeErrorMatrix.Rd

Defines probabilities for misreading ages.

Usage

DefineAgeErrorMatrix(
  processData,
  DefinitionMethod = c("ResourceFile"),
  FileName = character(),
  UseProcessData = F
)

Arguments

processData

AgeErrorMatrix as returned from this function

DefinitionMethod

'ResourceFile'. See details.

FileName

path to resource file

UseProcessData

If TRUE, bypasses execution of function and returns existing 'processData'

Value

Age Error Matrix, see: AgeErrorMatrix.

Details

Defines probabilities for misreading ages, that is assumed probabilites for determining a fish to be of age 'x' given that it actually is age 'y'.

Definitions are read from a tab separated file with headers and row names in first column. All row and column names should be integers representing ages. The matrix encodes the probability of observing an age (rows), given true age (columns), and columns must sum to 1.
