### Ethnicolr CLI - Examples

Source: https://pypi.org/project/ethnicolr

Practical examples demonstrating how to use the ethnicolr CLI for census data lookup and race/ethnicity prediction.

```APIDOC
## Examples
To append census data from 2010 to a sample file with column header in the first row, specify the column name carrying last names using the [`-l`] option, keeping the rest the same:
```
# Download the sample file first:
curl -O https://raw.githubusercontent.com/appeler/ethnicolr/refs/heads/master/examples/input-with-header.csv

# Then run census lookup:
census_ln -y 2010 -o output-census2010.csv -l last_name input-with-header.csv

```

To predict race/ethnicity using Wikipedia full name model, specify the column name of last name and first name by using [`-l`] and [`-f`] flags respectively.
```
pred_wiki_name -o output-wiki-pred-race.csv -l last_name -f first_name input-with-header.csv

```
```

--------------------------------

### Model Management

### Ethnicolr - Name Cleaning

Source: https://pypi.org/project/ethnicolr

Guidelines and recommendations for cleaning names before using ethnicolr prediction models to ensure optimal results.

```APIDOC
### Cleaning Names
The prediction models work best when first and last names contain only alphabetic characters. Before calling the CLI or Python APIs, strip out titles (e.g., _Dr_ , _Hon._), middle names, suffixes, punctuation and non-ASCII characters. The `pred_wiki_name` command automatically normalizes names by removing diacritics and extraneous characters. If the tool still skips entries, check that the first and last name columns are not empty after cleaning.
```

--------------------------------

### Predict Race using Wiki Last Name Model

### Predict Race with conf_int using pred_wiki_name

Source: https://pypi.org/project/ethnicolr

Appends race prediction columns to a DataFrame. Use `conf_int` to specify the confidence interval for predictions. The output includes mean, standard error, and confidence bounds for each predicted race.

```python
>>> odf = pred_wiki_name(df,'last', 'first', conf_int=0.9)
['Asian,GreaterEastAsian,EastAsian', 'Asian,GreaterEastAsian,Japanese', 'Asian,IndianSubContinent', 'GreaterAfrican,Africans', 'GreaterAfrican,Muslim', 'GreaterEuropean,British', 'GreaterEuropean,EastEuropean', 'GreaterEuropean,Jewish', 'GreaterEuropean,WestEuropean,French', 'GreaterEuropean,WestEuropean,Germanic', 'GreaterEuropean,WestEuropean,Hispanic', 'GreaterEuropean,WestEuropean,Italian', 'GreaterEuropean,WestEuropean,Nordic']
