In quanteda.textmodels: Scaling Models and Classifiers for Textual Data

Prediction from a textmodel_wordfish method

Description

predict.textmodel_wordfish() returns estimated document scores and confidence intervals. The method is provided for consistency with other ⁠textmodel_*()⁠ methods, but does not currently allow prediction on out-of-sample data.

Usage

## S3 method for class 'textmodel_wordfish'
predict(
  object,
  se.fit = FALSE,
  interval = c("none", "confidence"),
  level = 0.95,
  ...
)

## S3 method for class 'textmodel_wordfish'
coef(object, margin = c("both", "documents", "features"), ...)

coefficients.textmodel_wordfish(object, ...)

Arguments

object	a fitted wordfish model
se.fit	if TRUE, return standard errors as well
interval	type of confidence interval calculation
level	tolerance/confidence level for intervals
...	not used
margin	which margin of parameter estimates to return: both (in a list), or just document or feature parameters

Value

coef.textmodel_wordfish() returns a matrix of estimated parameters coefficients for the specified margin.
