MCMC Chain
class.
bound_names
names of bounds
slot in the original Scenario
object
contrast_names
names of contrasts
slot in the Scenario
object
gene_names
names of genes, taken from the row names of the count data matrix
library_names
names of the libraries/samples, taken from the column names of the count data matrix
proposition_names
names of propositions
slot in the Scenario
object
bounds
values to compare contrasts to. The comparison is to see if the contrast is greater than
its corresponding element in bounds
(from the Scenario
object)
contrasts
contrasts from the Scenario
object.
counts
RNA-seq count data, flattened from a matrix
design
Design, flattened from the design matrix. Original matrix must have rows corresponding to colums/libraries in RNA-seq data and colums corresponding to sets of gene-specific variables.
propositions
propositions of inequalities involving contrasts from the Scenario
object.
supplement
a list containing supplementary information about the scenario: for example, how the data were simulated, if applicable
burnin
MCMC burnin, the number of MCMC iterations to ignore at the beginning of each obj
effects_update_beta
bounds of l for which to update the beta_l, g parameters.
theta_update
Indices l for which theta_l is updated/sampled in the MCMC.
genes_return
Indices of genes whose parameter samples you want to return. Applies to all gene-specific parameters except for the epsilons.
genes_return_epsilon
Indices of genes g for which epsilon_n, g is updated/returned.
iterations
Number of MCMC iterations after burnin for which selected parameter samples are kept. Total MCMC iterations = burnin + thin * "iterations", and the whole "thin * iterations" portion is used to calculate posterior means, mean squares, and probabilities.
libraries_return
Indices of RNA-seq libraries whose parameter samples you want to return. Currently moot because there are no library-specific parameters other than the epsilons, but that could change in future versions of the package.
libraries_return_epsilon
Indices of RNA-seq libraries n for which epsilon_n, g is updated/returned. Applies to all library-specific parameters except for the epsilons.
parameter_sets_return
Character vector naming the variables whose MCMC samples you want to return
parameter_sets_update
Character vector naming the variables to calculate/update during the MCMC.
priors
Names of the family of priors on the betas after integrating out the xi's.
Can be any value returned by special_beta_priors()
. All other bounds will default to the normal prior.
samplers
character string specifying algorithm
thin
MCMC thinning interval. thin = 1
means parameter samples will be saved for every iterations
after burnin. thin = 10
means parameter samples will be saved every 10th iteration after burnin.
Total MCMC iterations = burnin + thin * "iterations", and the whole "thin * iterations" portion
is used to calculate posterior means, mean squares, and probabilities.
verbose
Number of times to print out progress during burnin and the actual MCMC.
If verbose
> 0, then progress messages will also print during setup and cleanup.
C
number of contrasts
countSums_g
gene-specific count sums
countSums_n
library-specific count sums
designUnique
Matrix of unique nonzero elements of design
. Vacent entries are 0.
designUniqueN
for each column index l
, number of unique nonzero elements of design[, l]
.
G
number of genes
Greturn
number of genes to return gene-specific MCMC parameter samples for (except the epsilons)
GreturnEpsilon
number of genes to return gene-specific MCMC epsilon parameter samples
L
number of columns in the original design matrix
Lupdate_beta
number of bounds of l for which to update the beta_l, g parameters.
Lupdate_theta
number of indices l for which to update the theta_l parameters.
N
number of libraries
Nreturn
number of libraries to return library-specific MCMC parameter samples for (except the epsilons)
NreturnEpsilon
number of libraries to return library-specific MCMC epsilon parameter samples
P
number of propositions involving contrasts
probs
estimated posterior probabilities of propositions in the Scenario
object.

betas, specified by the contrasts
slot.

betas, specified by the contrasts
slot.
