小弟最近在研究weka这一软件，请各位帮我看看这一个logistic regression的结果如何分析，万分感激，我不明白下面的数字是什么意思
Class 0 :
70.3 +
[newCellIndY] * 0.45 +
[newCellIndN] * 0.54 +
[birthDate] * 0
+
[svcStartDt] * 0
+
[incomeCode] * -0.01 +
[peakMinAv] * 0
+
[peakMinDiff] * 0
+
[posTrend] * 0.45 +
[negTrend] * 0.3
+
[nrProm] * 0.13 +
[prom] * -0.43 +
[planChange] * 0.06 +
[posPlanChange] * 0.21
