我一直在學習最近使用R RecordLinkage軟件包。在與連接2點的數據集,一個8行和其他11個非常小的例子,我得到的結果:R RecordLinkage軟件包,瞭解alpha和beta錯誤
Linkage Data Set
8 records in data set 1
11 records in data set 2
8 record pairs
4 matches
4 non-matches
0 pairs with unknown status
Weight distribution:
[0.4,0.5] (0.5,0.6] (0.6,0.7] (0.7,0.8] (0.8,0.9] (0.9,1]
2 0 2 0 1 3
3 links detected
0 possible links detected
5 non-links detected
alpha error: 0.250000
beta error: 0.000000
accuracy: 0.875000
Classification table:
classification
true status N P L
FALSE 4 0 0
TRUE 1 0 3
什麼我不理解,是阿爾法誤差,測試誤差和精度之間的關係與分類表。凡低於來自正是未來的數字,他們如何計算:
alpha error: 0.250000
beta error: 0.000000
accuracy: 0.875000
任何幫助,不勝感激
謝謝,非常清楚的解釋 –
