Dropping two values in a dependent variable of a regression in R

Question

If my y value for the regression has four values in the entire data (996, 997, 998, 999), I want to eliminate two values (996 and 999) when regressing on other variables. It is originally a Tobit, but for this sake I need to do a regular OLS regression. If you refer to the picture, essentially, I want to only consider the values that are valid (211). I'm not sure how to do this in R.

Answer 1

假设您将“ smoke_data”作为数据表，并将“ value”作为响应变量，这是一种排除不必要值的快速方法。

lm(value~.,data=smoke_data[smoke_data[,"value"]!=996 & smoke_data[,"value"]!=999, ])
