我有关于性别和请愿的数据。我想在“女性”(女性)变量和请愿书的不同问题之间做出回归。我已将这些问题重新分解为一般主题下的数据框架,这些主题是我想用“女性”(女性)变量回归的。
P.S。:一些请愿书有许多问题(例如:水+科学)。因此,一个请愿书可以同时计入两个数据框。1)这是我为所有问题所做的,这是一个带有“原住民”问题的例子,向您展示我如何编码初始问题(您还可以在开头看到“Femme”变量,这是已经在“女性”下的原始数据集中编码为“0”和“1”:
DataPetitions$Femme <- DataPetitions$Female
DataPetitions$Aboriginal <- NA
DataPetitions$Aboriginal[grepl("Aboriginal", DataPetitions$Issue)] <-1
DataPetitions$Aboriginal[!grepl("Aboriginal", DataPetitions$Issue)] <-0
# ... (same for all 24 specific issues)
2)为一般请愿主题创建7个数据框:
EnvironmentalIssues <- c(DataPetitions$AirQuality,DataPetitions$Biological, DataPetitions$Climate, DataPetitions$Environmental, DataPetitions$Toxic, DataPetitions$Waste, DataPetitions$Water)
EconomicIssues <- c(DataPetitions$Natural, DataPetitions$Transport)
SocialIssues <- c(DataPetitions$Aboriginal, DataPetitions$Health)
AgriculturalIssues <- c(DataPetitions$Agriculture,
DataPetitions$Fisheries, DataPetitions$Pesticides)
PoliticalIssues <- c(DataPetitions$Compliance, DataPetitions$Federal,
DataPetitions$Governance, DataPetitions$International)
ScientificIssues <- c(DataPetitions$Science)
OtherIssues <- c(DataPetitions$Other)
3)尝试做回归。这是我的glm代码:
model7 <- glm(DataPetitions$Femme ~ SocialIssues + PoliticalIssues +
ScientificIssues + EnvironmentalIssues + EconomicIssues +
AgriculturalIssues + OtherIssues, data = DataPetitions)
# When I try to run it, I get this error message:
Error in model.frame.default(formula = DataPetitions$Femme ~
SocialIssues + : variable lengths differ (found for
'SocialIssues')
使用dput(head(DataPetitions,20))
,我明白了:
