        # Get overall bucket results.
        # Retrievs overall bucket results that summarize the bucket results of
        # multiple anomaly detection jobs.
        # The +overall_score+ is calculated by combining the scores of all the
        # buckets within the overall bucket span. First, the maximum
        # +anomaly_score+ per anomaly detection job in the overall bucket is
        # calculated. Then the +top_n+ of those scores are averaged to result in
        # the +overall_score+. This means that you can fine-tune the
        # +overall_score+ so that it is more or less sensitive to the number of
        # jobs that detect an anomaly at the same time. For example, if you set
        # +top_n+ to +1+, the +overall_score+ is the maximum bucket score in the
        # overall bucket. Alternatively, if you set +top_n+ to the number of jobs,
        # the +overall_score+ is high only when all jobs detect anomalies in that
        # overall bucket. If you set the +bucket_span+ parameter (to a value
        # greater than its default), the +overall_score+ is the maximum
        # +overall_score+ of the overall buckets that have a span equal to the
        # jobs' largest bucket span.
        #
        # @option arguments [String] :job_id Identifier for the anomaly detection job. It can be a job identifier, a
        #  group name, a comma-separated list of jobs or groups, or a wildcard
        #  expression.You can summarize the bucket results for all anomaly detection jobs by
        #  using +_all+ or by specifying +*+ as the +<job_id>+. (*Required*)
        # @option arguments [Boolean] :allow_no_match Specifies what to do when the request:
        #  - Contains wildcard expressions and there are no jobs that match.
        #  - Contains the +_all+ string or no identifiers and there are no matches.
        #  - Contains wildcard expressions and there are only partial matches.
        #  If +true+, the request returns an empty +jobs+ array when there are no
        #  matches and the subset of results when there are partial matches. If this
        #  parameter is +false+, the request returns a +404+ status code when there
        #  are no matches or only partial matches. Server default: true.
        # @option arguments [Time] :bucket_span The span of the overall buckets. Must be greater or equal to the largest
        #  bucket span of the specified anomaly detection jobs, which is the default
        #  value.By default, an overall bucket has a span equal to the largest bucket span
        #  of the specified anomaly detection jobs. To override that behavior, use
        #  the optional +bucket_span+ parameter.
        # @option arguments [String, Time] :end Returns overall buckets with timestamps earlier than this time.
        # @option arguments [Boolean] :exclude_interim If +true+, the output excludes interim results.
        # @option arguments [Double, String] :overall_score Returns overall buckets with overall scores greater than or equal to this
        #  value.
        # @option arguments [String, Time] :start Returns overall buckets with timestamps after this time.
        # @option arguments [Integer] :top_n The number of top anomaly detection job bucket scores to be used in the
        #  +overall_score+ calculation. Server default: 1.
        # @option arguments [Hash] :headers Custom HTTP headers
        # @option arguments [Hash] :body request body
