Compute credible intervals for expected measurements
Source:R/get_expected.R
getExpectedMeasIntervals.Rd
This functions uses posterior samples to quantify uncertainty in the expected measurements from fitted models.
Usage
getExpectedMeasIntervals(expectedMeas, mass = 0.9, method = c("eti", "hdi"))
Arguments
- expectedMeas
A
data.table
of expected measurements for posterior samples, as returned bygetExpectedMeas()
.- mass
Number between 0 and 1 indicating the probability mass for which to calculate the intervals.
- method
String indicating the type of interval: 'eti' for equal-tailed using
stats::quantile()
, or 'hdi' for highest density usingHDInterval::hdi()
.
Value
A data.table
containing lower and upper bounds of the expected
measurement for each combination of feature, time, and possibly condition
and covariate.
Examples
library('data.table')
y = GSE34018$y
metadata = GSE34018$metadata
fit = getModelFit(y, metadata)
fit = getPosteriorFit(fit)
fit = getPosteriorSamples(fit, nPosteriorSamples = 10L)
measFitSamps = getExpectedMeas(
fit, times = seq(0, 24, 0.5), fitType = 'posterior_samples',
features = c('13170', '12686'))
measFitInts = getExpectedMeasIntervals(measFitSamps)
