Statistics for Data Science

Step 4: Reviewing the model

Perhaps the final step in our process is to create a summation of the model and review it for statistical significance.

We can use the R function summary:

# --- generate the summary of the model  
 
summary (lmMod)

This generates the following output:

From the preceding output generated, we are shown that our model predictor's p values are visually interpreted as significant, shown by the significance stars at the end of the row (outlined), so we know we have a statistically significant model.
