# PERCENTILEOFVALUE

PERCENTILEOFVALUE(`series 1`, `series 2`)

Returns the percentile of a given value, or series of values, given an input set of data.

### Arguments

| Input          | Description                                 |
| -------------- | ------------------------------------------- |
| `target value` | Target value(s) to return percentile for    |
| `data`         | Series of data to calculate percentile from |

### Outputs

Returns a percentile or series of percentiles.

### Example

Let's say we have a series of ages and we wish to know what percentile a 26 year-old would be in. Using `MODELPERCENTILE(26, {Age})` will allow us to calculate that.

Now let's say that we wish to know what percentile each age in our dataset is. If we input `MODELPERCENTILE({Age}, {Age})`, we will get a corresponding percentile value for each age.
