How many parameters, including the intercept, are associated with this model?
A linear model has the following characteristics:*A dependent variable (y)*One continuous variable (xl), including a quadratic term (x12)*One categorical (d with 3 levels) predictor variable and an interaction term (d by x1).
The answer to this is 7. There are different ways that a linear model can be defined depending on how it is used. For example, there are some that would define the linear model as something that is used in connection to regression models. The linear model can also be used for a time series analysis.
It will depend on what you are searching for so that you can properly define it. There are different features that will make up the linear model. Its main goal is to make sure that you will consider each feature properly so that an estimated value will come up.
