本文介绍了为什么在AIC中的AIC期间行数会改变?如何确保不会发生这种情况?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试在R中使用AIC查找一个最小的适当模型.我不断收到以下错误: 步骤(模型)错误: 使用中的行数已更改:要删除缺少的值吗?
I'm trying to find a minimal adequate model using AIC in R. I keep getting the following error: Error in step(model) : number of rows in use has changed: remove missing values?

#NOTE: this will have to be adjusted to your particular directory
pipeline_dir='/Users/mf/Desktop/pipeline/'
response='QnWeight_initial'
predictors=c('HL','V1','V2')
predictor_filename='HL_V1_V2'
model <- lm(formula=as.formula(paste(paste(response,'~', sep=''),paste(predictors,collapse='+'), sep='')),data)
sink(file=paste(paste(pipeline_dir,'MAMs/', sep=''),paste(paste(paste(response, 'on', sep=''), predictor_filename, sep=''),'_fullModel.txt', sep='')))
print(summary(model))
sink()
sink(file=paste(paste(pipeline_dir,'MAMs/', sep=''),paste(paste(paste(response, 'on', sep=''), predictor_filename, sep=''),'.txt', sep='')))
step(model)
sink()
推荐答案
从?step的警告"部分:
所以您应该这样做:
no.na.data <- na.omit(data[c(predictors, response)])
model <- lm(formula=as.formula(paste(paste(response,'~', sep=''),
paste(predictors,collapse='+'), sep='')),
no.na.data)
step(model)
