Question

Exercise 8.12 introduces data on the average monthly temperature during the month babies rst try to crawl (about 6 months after birth) and the average rst crawling age for babies born in a given month. A scatterplot of these two variables reveals a potential outlying month when the average temperature is about 53F and average crawling age is about 28.5 weeks. Does this point have high leverage

Answer 1

Answer:

The point has a high leverage

Step-by-step explanation:

The point has a high leverage as it would act as an infinitesimal point that will have a very huge/drastic  impact on the fit of the model, and this impact can be seen in such ways as listed below :

• Smaller coefficient of determination
• Higher sum of squares error

removing this point will eliminate these drastic impact and make the correlation to be better.
