A web service that receives a JSON paylod of samples and returns a JSON payload the random uncertanity of the samples

run locally:

install uv

uv sync

install the python modules, enter the .venv and run the application

uv sync
flask --app webuncert/app run
uv run flask --app webuncert/app run --port=5000 --host=0.0.0.0

Build and run it as a docker container

create a docker container and run it, and mapping it to port 1000 on the dockerhost machine.

docker build -t webuncert .
docker container run -d -p 1000:5000 webuncert

how to use the webservice

it is the /calc route, you can give a GET or POST request with: input HTTP body:

{"samples": [1000.1, 999.9, 1000.0, 998.9, 1000.0, 1000.8, 1002.7]}

returns:

    "uncertanity_from_repetatbilty": true,
}

valid JSON raw input:

 {
    "samples": [1000.1, 999.9, 1000.0, 998.9, 1000.0, 1000.8, 1002.7],
    "stdev": "bool",
    "confidence_interval": "0.0-1.0 or 1-100%",
    "coverage_factor": "float", 
 }

Note: if both confidence_interval and coverage factor is sent in the body, then coverage factor base uncert will be returned.
