likelihood_map {alien}R Documentation

Plot log-likelihood space

Description

Plot a filled-contour heatmap displaying the log-likelihood space calculated using likelihood_space.

Usage

likelihood_map(likelihood_space, x, y, delta = 10)

Arguments

likelihood_space

a data frame resulting from a call to likelihood_space, where columns represent parameter values and an extra column log_likelihoods with the corresponding log-likelihood for each parameter value combination.

x

a string specifying the parameter to be plotted on the x-axis.

y

a string specifying the parameter to be plotted on the y-axis.

delta

the range of log-likelihood values of which different color codes will be plotted. Defaults to 10.

Value

#' A ggplot plot with the corresponding type of plot.

Examples


if (FALSE){ # takes a while to finish
example_model <- snc(sfestuary)
estimates <- example_model$coefficients$Estimate

likelihood_space <- likelihood_space(y = sfestuary, centers = estimates,
                                     ranges = 1.5, steps_from_center = 10,
                                     calculate = TRUE)

likelihood_map(likelihood_space, "beta0", "beta1", 10)
 }
