Best_Model function

Find Best Model

This function will try to find out a significant model for each combinations based on adjusted R^2. Then user need to select which model they want to use.

Best_Model(model, data)

Arguments

• model: Provide a vector that contains all the individual terms present in a full model
• data: Provide data in a matrix or data frame format where you want to fit the model

Returns

Generate a list of significant models for various combinations of factors.
