Linear Regression Calculation differences
Posted: Sat Mar 23, 2024 10:49 am
Dear All,
I have a data set consist of 2 factors and 1 output variable. I would like to perform linear regression with the base Jamovi modul.
The calculated ANOVA (Omnibus ANOVA test) is good (pic1.jpg).
The next step is to take into account the interaction to the model. In this case the calculated ANOVA table is and the modell coefficients (pic2.jpg).
When I have repeated it with the Linear Models modul, there the calculation is different(pic3.jpg).
If the variable is take into account as factor, then the ANOVA is the same. If the variable is take into account as covariates the results are different.
Could you explain the received difference?
Best regards,
Agota
