Description

Methods for function linearComb in Package `unmarked'

Methods

obj = "unmarkedEstimate", coefficients = "matrixOrVector"

Typically called internally

obj = "unmarkedFit", coefficients = "matrixOrVector"

Returns linear combinations of parameters from a fitted model. Coefficients are supplied through coefficients. The required argument type specifies which model estimate to use. You can use names(fittedmodel) to view possible values for the type argument.

Examples

data(ovendata)
ovenFrame <- unmarkedFrameMPois(ovendata.list$data,
siteCovs=as.data.frame(scale(ovendata.list$covariates[,-1])), type = "removal")
fm <- multinomPois(~ 1 ~ ufc + trba, ovenFrame)
linearComb(fm, c(1, 0.5, 0.5), type = "state")
linearComb(fm, matrix(c(1, 0.5, 0.5, 1, 0, 0, 1, 0, 0.5), 3, 3,
  byrow=TRUE), type="state")
