weighted_mean

Computes a weighted mean of a vector, matrix, or a three dimensional array.

Fast functions for effective sample size, weighted multivariate
mean, variance, and quantile computation, and weight diagnostic plot for
generic importance sampling type or other probability weighted samples.

weighted_mean function

<dl><dt>x</dt>
<dd>A numeric vector, matrix, three dimensional array, or an <code>mcmc</code> object from
the <code>coda</code> package. For matrix, the mean is computed for each column, and 
for array the sweep is done over the third dimension.</dd>
<dt>w</dt>
<dd>A numeric vector of non-negative weights. Will be automatically normalised to sum to one.</dd>
<dt>na.rm</dt>
<dd>If <code>TRUE</code>, <code>NA</code> values in <code>x</code> (and corresponding weights in <code>w</code>) are
omitted from the computation. Default is <code>FALSE</code>. Only used in vector methods.</dd></dl>
