H2O的收益/升力表的列定义是什么? [英] What are the column definitions for H2O's gains/lift table?

问题描述

H2O的文档没有为增益/提升表输出中的每一列提供明确的定义.我不确定捕获率是如何计算的，并且文档中没有提到 score 列.

H2O's documentation doesn't provide clear definitions for each column in the gains/lift table output. I'm not sure how the capture rate is being calculated, and there is a score column that is not mentioned in the documentation.

输出内容如下.

推荐答案

对于表中给定的x行:

cumulative_data_fraction =第x组中的数字/所有观察值

cumulative_data_fraction = number in group x / all observations

lower_threshold =组x中的最小预测概率

lower_threshold = minimum of predicted probability in group x

提升=响应率/总体响应率(即第16组中的累积响应率")

lift = response_rate / overall response rate (i.e., cumulative_response_rate in group 16)

cumulative_lift =累积响应率/总体响应率

cumulative_lift = cumulative_response_rate / overall response rate

response_rate =组x中的响应百分比

response_rate = percent of responses in group x

得分= x组中预测概率的平均值

score = average of predicted probability in group x

cumulative_response_rate =第1组到第x组中所有观察的响应率

cumulative_response_rate = response rate for all observations in groups 1 through x

cumulative_score =第1组到第x组中所有观测值的预测概率的平均值

cumulative_score = average of predicted probability for all observations in groups 1 through x

capture_rate = x组中所有响应的百分比

capture_rate = percent of all responses that are in group x

cumulative_capture_rate =第1组到第x组中所有响应的百分比

cumulative_capture_rate = percent of all responses that are in groups 1 through x

增益=(提升-1)* 100

gain = (lift - 1) * 100

cumulative_gain =(累计累加-1)* 100

cumulative_gain = (cumulative_lift - 1) * 100
