## weightedZISpearman

### Description

the weightedZISpearman function calculates weighted rho\*, where rho\* is described in Pimentel et al (2009). This association measure is defined for zero-inflated, non-negative random variables.

### Usage

    weightedZISpearman(x, y, w = 1)

### Arguments

`x` | x and y are non-negative data vectors
`y` | x and y are non-negative data vectors
`w` | weight vector, values should be between 0 and 1

### Value

`numeric` weighted rho* association value between x and y

### Examples

    x = pmax(0,rnorm(100))
    y = pmax(0,rnorm(100))
    w = runif(100)
    weightedZISpearman(x,y,w)
