如何从函数Anova()中提取残差和读取系数？

# 假设你已经拟合了一个ANOVA模型并存储在变量model中
residuals <- residuals(model)

# 提取系数
coefficients <- coefficients(model)
# 或者
coefficients <- model$coef

# 安装并加载car包
install.packages("car")
library(car)

# 创建一个示例数据集
data <- data.frame(
  group = factor(rep(1:3, each = 10)),
  value = c(rnorm(10, 10, 2), rnorm(10, 15, 2), rnorm(10, 20, 2))
)

# 拟合ANOVA模型
model <- lm(value ~ group, data = data)

# 执行ANOVA分析
anova_result <- Anova(model)

# 提取残差
residuals <- residuals(model)

# 提取系数
coefficients <- coefficients(model)

# 打印结果
print(anova_result)
print(residuals)
print(coefficients)
