家族中的錯誤：poisson（link =「log」）：NA/NaN參數

Question

我想用功能glm()中建立的R來預測足球比賽結果。但是我得到Error in family:poisson(link = "log") : NA/NaN argument。

，我使用的代碼是：

model <- glm(HomeTeamScore ~ AwayTeamScore + HomeTeam + AwayTeam, 
      family:poisson(link = "log"), data = results) 
summary(model) 

結果如下表所示： -

Day  Date HomeTeam AwayTeam HomeTeamScore AwayTeamScore Competition 
1 Friday 2015-08-14 Aston Villa Man United    0    1 PremierLeague 
2 Monday 2015-08-10 West Brom Man City    0    3 PremierLeague 
3 Monday 2015-08-17 Liverpool Bournemouth    1    0 PremierLeague 
4 Monday 2015-08-24  Arsenal Liverpool    0    0 PremierLeague 
5 Monday 2015-09-14 West Ham Newcastle    2    0 PremierLeague 
6 Monday 2015-09-28 West Brom  Everton    2    3 PremierLeague 

Answer 1

您需要=而不是:

family = poisson(link = "log")
