chainladder.read_json(json_str, array_backend=None)[source]#

Deserialize JSON produced by to_json (triangle, estimator, or pipeline).

Examples

to_json serializes an estimator’s parameters as a JSON string that can be stored in a database, config file, or REST API. read_json reconstructs the estimator with all parameters intact.

dev = cl.Development(average="simple", n_periods=4)
json_str = dev.to_json()
print(json_str)
dev2 = cl.read_json(json_str)
print(dev2.get_params()["average"])
print(dev2.get_params()["n_periods"])
