Compute residuals and fitted values from functional demographic model or Lee-Carter model
After fitting a Lee-Carter model or functional demographic model, it is useful to inspect the residuals or plot the fitted values. These functions extract the relevant information from the fit object.
## S3 method for class 'fdm' residuals(object, ...) ## S3 method for class 'fdm' fitted(object, ...) ## S3 method for class 'lca' fitted(object, ...) ## S3 method for class 'lca' residuals(object, ...)
residuals.fdm and residuals.lca produce an object of
class “fmres” containing the residuals from the model.
fitted.fdm and fitted.lca produce an object of class
“fts” containing the fitted values from the model.
