Installation

eseas

You can install the eseas package via pip:

pip install eseas

Alternatively, you can install it from a local wheel file:

pip install ./eseas-0.1.0-py3-none-any.whl

jwsacruncher

The jwsacruncher tool is required for this package to function. You can download the latest release of jwsacruncher from the jdemetra releases.

# Download jwsacruncher
cd jdemetra/jswacruncher

After downloading jwsacruncher, you need to specify its location when using the Options function from the eseas package.

Usage

Here's an example of how to use the eseas package:

from eseas import Seasonal, Options
import time

def main():
    # Specify the path to the jwsacruncher bin directory
    java_folder = r'../jwsacruncher-2.2.4/bin'
    demetra_source_folder = r"./demetra_source_folder"
    local_folder = r"./test_out"

    options = Options(
        demetra_source_folder,
        java_folder,
        local_folder,
        result_file_names=("sa", "s_f", "cal"), # *1 
         
        workspace_mode=True,
        file_name_explanation=True,
    )
    # Note (1)
    # result_file_names see full list of result types from Demetra Components below

    seas = Seasonal(options)
    
    seas.part1()
    time.sleep(10)
    seas.part2()

if __name__ == "__main__":
    main()
