Simple function that normalize vectors (ie takes log weights and returns normalized weights,
in the SMC context).
Usage
normalizeweight(log_weights)
Arguments
log_weights
Object of class "numeric": a real-valued vector
Value
The function returns an object of class "data.frame", with columns for the chain indices, the chain values,
the iteration indices, and the associated log density values.
Details
Simple function that takes log weights (ie any real-valued vector), computes
the exponential of it, divides it by its sum and returns it.
