Закономерность №1
Если фирма = Rekam ТО цена = 4799
Condition Fields:
firma is Rekam
Dependent Variable: cena
Subject for Prediction: cena is between 4 798,00 and 4 799,00
Primary Prediction's probability: 0,067
Conclusive Prediction's probability: 0,000
Decision point: 0,478
Prediction: No between 4 798,00 and 4 799,00
The following conditions explain when cena is between 4 798,00 and 4 799,00
When at least one of the conditions holds, the probability that
cena is between 4 798,000 and 4 799,000
is 1,000 (4 out of 4 cases)
When all the conditions do not hold, the probability that
