    linear regression

    I'm running a simple linear regression with one explanatory variable.

    however my constant term is insignificant (P>0.05). What is the implication of this? How do I interpret/remedy an insignificant constant?

    thanks

    I have decided to exclude constant term as it is insignificant, my issue is how to interpret this. My dependent is ice lolly sales data so intuitively I would expect a base level of sales over time regardless of all other factors.

    I know an insignificant constant means I'm missing explanatory factors but I only have data for one factor in this case (average temperature).
