Computer-implemented method for updating a model parameter for a model, wherein the model parameter to be updated comprises a model parameter value and a confidence score; comprising the steps: characterized in that a. Providing the model parameter to be updated, a first input data set with data accumulated since a first or previous update, a second input data set with data accumulated and used for the first or previous update (S1); b. Determining a statistical significance of the first input data set and/or the second input data set regarding at least one condition to perform the update (S2); c. Determining an updated model parameter using an estimation approach based on the model parameter to be updated and the first input data set, if the first input data set is statistically significant (S3); wherein the updated model parameter comprises an updated model parameter value and an updated confidence score; if the first input data set does not meet the at least one condition, the update is prevented; or the first input data set is extended with the second input data set and the update is performed on the extended data; d. Determining an updated model parameter using an estimation approach based on the model parameter to be updated, the first input data set and the second input data set or maintain the model parameter to be updated as the updated model parameter, if the first input data set and the second input data set are not statistically significant (S4); and e. Providing the determined updated model parameter as output (S5). a.
