predict.tinyVAST: Predict using vector autoregressive spatio-temporal model

In tinyVAST: Multivariate Spatio-Temporal Models using Structural Equations

Predict using vector autoregressive spatio-temporal model

Description

Predicts values given new covariates using a tinyVAST model

Usage

## S3 method for class 'tinyVAST'
predict(
  object,
  newdata,
  remove_origdata = FALSE,
  what = c("mu_g", "p_g", "p1_g", "palpha1_g", "pgamma1_g", "pepsilon1_g", "pomega1_g",
    "pdelta1_g", "pxi1_g", "p2_g", "palpha2_g", "pgamma2_g", "pepsilon2_g", "pomega2_g",
    "pdelta2_g", "pxi2_g"),
  se.fit = FALSE,
  bias.correct = FALSE,
  ...
)

Arguments

object	Output from tinyVAST().
newdata	New data-frame of independent variables used to predict the response.
remove_origdata	Whether to eliminate the original data from the TMB object, thereby speeding up the TMB object construction. However, this also eliminates information about random-effect variance, and is not appropriate when requesting predictive standard errors or epsilon bias-correction.
what	What REPORTed object to output, where mu_g is the inverse-linked transformed predictor including both linear components, p_g is the sum of the first and second linear predictors (which only makes sense to inspect when using the Poisson-linked delta model), p1_g is the first linear predictor, palpha_g is the first predictor from fixed covariates in formula, pgamma_g is the first predictor from random covariates in formula (e.g., splines), pomega_g is the first predictor from spatial variation, pepsilon_g is the first predictor from spatio-temporal variation, pxi_g is the first predictor from spatially varying coefficients, p2_g is the second linear predictor, palpha2_g is the second predictor from fixed covariates in formula, pgamma2_g is the second predictor from random covariates in formula (e.g., splines), pomega2_g is the second predictor from spatial variation, pepsilon2_g is the second predictor from spatio-temporal variation, and pxi2_g is the second predictor from spatially varying coefficients.
se.fit	Calculate standard errors?
bias.correct	whether to epsilon bias-correct the predicted value
...	Not used.

Value

Either a vector with the prediction for each row of newdata, or a named list with the prediction and standard error (when se.fit = TRUE).
