R: Log-Density for Multinomial Distribution

ldmult {mixtools} | R Documentation

## Log-Density for Multinomial Distribution

### Description

Return the logarithm of the multinomial density function.

### Usage

    ldmult(y, theta)

### Arguments

`y` | A vector of multinomial counts.
`theta` | A vector of multinomial probabilities. May have same number of components as or one fewer component than `y`. In the latter case, an extra component is appended so that theta sums to one.

### Details

This function is called by `multmixEM`.

### Value

`ldmult` returns the logarithm of the multinomial density with parameter `theta`, evaluated at `y`.

### See Also

`multmixEM`

### Examples

    y <- c(2, 2, 10)
    theta <- c(0.2, 0.3, 0.5)
    ldmult(y, theta)
