How to estimate 'Regression with and without a var on display'

[SirCee]

Hello All,

Could you help me figure out how to est. a regression of a var (example B) on a var (example C) when var A is on display.

ALSO, Could you help me figure out how to estimate a regression of a var (example B) on a var (example C) when var A is NOT on display.

Thank you

What do you mean by on display? You could mean including a variable and comparing two models - but by which metric? What's your end goal? Or you could be meaning including an indicator variable that has two levels and you need to include it as a categorical variable and test the significance.

We were asked to 'Estimate a regression of A on B when A is on display' and then '.... When A is not on display'.

The question is not clear tbh. I may have to seek further clarification.
