The IF, THEN construct is used in association rule mining to replicate market basket analysis. When a customer buys bread, he is likely to also buy butter. Examples of association rules include the following: "Bread" -> "Butter"

Learn the following definitions to better understand market basket analysis:

● Antecedent

The entities or "itemsets" produced from the data are called antecedents. To put it another way, it's the IF element on the left. In the situation before, bread serves as the antecedent.

The term "consequent" refers to an item or group of items that are encountered along with the antecedent. The THEN part of the sentence is displayed on the right-hand side. The result in the aforementioned case is butter.

They are trying to determine how many transactions, how much lift, trust, and support there is for the two things, a phone, and a phone cover, out of 5000. The phone has 500 transactions, the phone case has 800 transactions, and the two together have 1000 transactions.
