我想知道是否有人可以利用我拥有的以下数据将我指向正确的方向。
数据快照如下所示：
PANID WEEK brandID mariedstatus educ_male_HH educ_fem_HH
1 1100016 2001-03-19 48 2 2 3
2 1100016 2001-07-30 48 2 2 3
3 1100016 2001-12-17 48 2 2 3
4 1100057 2001-06-11 209 2 5 6
5 1100057 2001-06-18 207 2 5 6
6 1100057 2001-06-18 217 2 5 6
所以我有关于人（PANID），他们购买了特定品牌的WEEK和brandID的数据。然后是一些人口统计学，婚姻状况，男性家庭教育，女性家庭教育等。
我正在尝试计算条件概率，因此鉴于PANID在brandID-48上购买了WEEK号2001-03-19的事实，概率是多少，他们会再次购买同一品牌。
所以我只是在寻找一些有关如何解决该问题的建议/代码。
我曾考虑过要创建一个二进制变量来确定一个人在一年中是否多次购买同一品牌
df %>%
group_by(PANID, brandID) %>%
mutate(user_total_brand_purchases = n()) %>%
mutate(reordered = ifelse(user_total_brand_purchases > 1, 1, 0))
但是我不确定这是否可以解决我的问题。
