## Weighted Median

### Description

Compute a weighted median of a numeric vector.

### Usage

weighted.median(x, w, na.rm = FALSE)

### Arguments

`x` |
a numeric vector containing the values whose mean is to be computed. |

`w` |
a vector of weights the same length as `x` giving
the weights to use for each element of `x` . |

`na.rm` |
a logical value indicating whether `NA`
values in `x` should be stripped before the computation proceeds. |

### Details

If `w`

is missing then all elements of `x`

are
given the same weight.

Missing values in `w`

are not handled.

The weighted median is the median of the discrete distribution with
values given by `x`

and probabilities given by `w/sum(w)`

.

### Value

numeric value giving the weighted median
