A class of the output from 'SpaTopic'
Description
Outputs from function SpaTopic_inference.
A list contains the following members:
-
$Perplexity. The perplexity is for the training data. Let N be the total number of cells across all images.Perplexity = exp(-loglikelihood/N) -
$Deviance.Deviance = -2loglikelihood. -
$loglikelihood. The model log-likelihood. -
$loglike.trace. The log-likelihood for every collected posterior sample. NULL iftrace= FALSE. -
$Beta. Topic content matrix with rows as celltypes and columns as topics -
$Theta. Topic prevalent matrix with rows as regions and columns as topics -
$Ndk. Number of cells per topic (col) per region (row). -
$Nwk. Number of cells per topic (col) per celltype (row). -
$Z.trace. Number of times cell being assigned to each topic across all posterior samples. We can further compute the posterior distributions ofZ(topic assignment) for individual cells. -
$doc.trace.Ndkfor every collected posterior sample. NULL iftrace= FALSE. -
$word.trace.Nwkfor every collected posterior sample. NULL iftrace= FALSE.
