ldmppr (version 1.1.0)

ldmppr_fit: Fitted point-process model object

Description

Objects of class `ldmppr_fit` are returned by [estimate_process_parameters()]. They contain the best-fitting optimization result (and optionally multiple fits, e.g. from a delta search) along with metadata used to reproduce the fit.

Usage

# S3 method for ldmppr_fit
print(x, ...)

# S3 method for ldmppr_fit coef(object, ...)

# S3 method for ldmppr_fit logLik(object, ...)

# S3 method for ldmppr_fit summary(object, ...)

# S3 method for summary.ldmppr_fit print(x, ...)

# S3 method for ldmppr_fit plot(x, ...)

as_nloptr(x, ...)

# S3 method for ldmppr_fit as_nloptr(x, ...)

Value

* `print()` prints a brief summary of the fit. * `coef()` returns the estimated parameter vector. * `logLik()` returns the log-likelihood at the optimum. * `summary()` returns a `summary.ldmppr_fit`. * `plot()` plots diagnostics for multi-fit runs (e.g. objective vs delta), if available.

Arguments

x

an object of class `ldmppr_fit`.

...

additional arguments (not used).

object

an object of class `ldmppr_fit`.

Methods (by generic)

  • print(ldmppr_fit): Print a brief summary of a fitted model.

  • coef(ldmppr_fit): Extract the estimated parameter vector.

  • logLik(ldmppr_fit): Log-likelihood at the optimum.

  • summary(ldmppr_fit): Summarize a fitted model.

  • plot(ldmppr_fit): Plot diagnostics for a fitted model.

  • as_nloptr(ldmppr_fit): Extract the underlying `nloptr` result.

Functions

  • print(summary.ldmppr_fit): Print a summary produced by [summary.ldmppr_fit()].

  • as_nloptr(): Extract the underlying `nloptr` result.

Details

A `ldmppr_fit` is a list with (at minimum):

  • `process`: process name (e.g. `"self_correcting"`)

  • `fit`: best optimization result (currently an `nloptr` object)

  • `mapping`: mapping information (e.g. chosen `delta`, objectives)

  • `grid`: grid definitions used by likelihood approximation
