I have a query on how to interpret the result for multiple regression with categorical variables. I have categorical variable called Stay_In_current_city_years which has 5 levels. After running the linear model I get an output with 4 different p-values.
How do I interpret this result? Does it mean that Stay_In_current_city_years1 with p-value=.0746 is not a significant predictor and Stay_In_Current_City_Years2 with p-value=.005 is a significant predictor? If so how would remove the variables which are not statistically significant? Thanks
