ebb_mixture_tidiers: Tidy a mixture of beta-binomials

In dgrtwo/ebbinom: Empirical Bayes on binomial data

Description

Tidy a mixture model fit by ebb_fit_mixture. tidy returns in the hyperparameters fit for each cluster, while glance returns the likelihood and other parameters for the full mixture.

Usage

## S3 method for class 'ebb_mixture'
tidy(x, ...)

## S3 method for class 'ebb_mixture'
augment(x, data, ...)

## S3 method for class 'ebb_mixture'
glance(x, ...)

Arguments

x	An ebb_mixture object, such as returned by ebb_fit_mixture.
...	Extra arguments, not used
data	The original data that the mixture model was fit on

Value

tidy returns a tbl_df with one row for each cluster, with columns

cluster	A character vector with cluster IDs
alpha	alpha shape parameter for this cluster
beta	beta shape parameter for this cluster
mean	alpha / beta, the mean of the beta distribution
size	Size of this cluster in the final assignments
probability	Prior probability of being in this cluster

glance returns a one-row data frame with columns:

iter	Number of iterations
logLik	Log-likelihood of the model, given the final "hard" assignments to each cluster
AIC	AIC of the model
BIC	BIC of the model
