I used LM model with (categorical) predictor variables on my data in r like this (I have count variable as dependent/target variable):
# Fit linear model to total viewing: fit <- lm( total_viewing_minutes ~ panelist + sex + internet + education, data = cln )
If I understood correctly in r the first category is always the reference one so has by definition a coefficient of 0.
So by looking at the model result, is 68.3 minutes (intercept) average time viewing of
Panelist0 + sex1 + internet1 + education1
and by taking into account the term Panelist1
the 68.4 + 17.6 is avg time viewing of
Panelist1 + sex1 + internet1 + education1
is that correct interpretation?
