conditional(object, v, val)

Arguments

`object`	A multivariate probability distribution.

`val`	A vector, of the same length as `v`, with the values at which these variables should be fixed.

Examples

prior <- normalexpgamma() #Generate a two-parameter flat prior
full <- linearpredict(prior, rep(1, 7)) #Normal extension
data <- simulate(uniformdistribution(), 7) #Generate data
posterior <- conditional(full, 1:7, data) #Condition on parameters
credibilityinterval(marginal(posterior, 1)) #Investigate posterior
