I am working on a regression and I have a factor variable "Marital Status"
Marital status has 5 levels: Single, Married, Divored, Widowed, Other (don't ask me what constitutes someone being an 'other')
When I put this into R it will turn this one variable into 5-1=4 dummy variables and will give me this output
with divorced as the baseline.
My question is, can I only use the significant dummy variables? I would drop the variables for 'other' and 'widowed' and keep 'married' and 'single'
