Question

我想在R中找到一个命令，以便计算给定变量集的所有可能模型。例如，对于三个变量x1，x2和x3，有8种可能的模型：

  "dependencies": {
    "react": "16.0.0",
    "react-native": "0.51.0"
  },
  "devDependencies": {
    "@types/jest": "^22.0.1",
    "@types/react": "^16.0.34",
    "@types/react-native": "^0.51.9",
    "babel-jest": "22.0.4",
    "babel-preset-react-native": "4.0.0",
    "concurrently": "^3.5.1",
    "jest": "22.0.4",
    "react-test-renderer": "16.0.0",
    "rimraf": "^2.6.2",
    "tslint": "^5.8.0",
    "typescript": "^2.6.2"
  },

如果我有5个变量，则有6894个不同的模型（包括所有可能的交互），但我想用R确认。

Answer 1

答案是here

options(na.action = "na.fail") # avoid getting an error

library(MuMIn)

fullmodel <- lm(y ~ x1 * x2 * x3)

dredge(fullmodel, fixed = ~ x1 + x2 + x3)
