compute.link: Compute estimates of link values

In RMark: R Code for Mark Analysis

Compute estimates of link values

Description

Computes link values (design*beta) for real parameters, and var-cov from design matrix (design) and coefficients (beta)

Usage

compute.link(
  model,
  beta = NULL,
  design = NULL,
  data = NULL,
  parm.indices = NULL,
  vcv = TRUE
)

Arguments

model	MARK model object
beta	Estimates of beta parameters
design	numeric design matrix for MARK model with any covariate values filled in
data	dataframe with covariate values that are averaged for estimates
parm.indices	index numbers from PIMS for rows in design matrix to use
vcv	logical; if TRUE, returns v-c matrix of link values

Details

This function is very similar to compute.real except that it provides estimates of link values before they are transformed to real estimates using the inverse-link. It is called by get.link to make calculations but can be called separately. The value is always a dataframe for the estimates and design data and optionally a variance-covariance matrix. See get.real for further details about the arguments.

Value

estimates: If vcv=TRUE, a list is returned with elements vcv.link and the dataframe estimates. If vcv=FALSE, only the estimates dataframe is returned which has the same structure as in get.real.
