What does the negative coefficient on the quadratic term imply about the relationship between birth weight and prenatal visits? Does the sign make sense? Explain.
Answer: The fluctuations in the rates of Negative coefficients and Birth weight and prenatal visits of a specific population may be due to the following factors:
1. Adjustment problems of the women of the birth giving ages have become drastic.
2. Lack of proper availability of food and other facilities is may be another declining factor of the fluctuating ratios of Negative coefficients Rates and Birth weight and prenatal visits Rates.
3. When comparing stage 4 with that of stage 1, it is analyzed that the children which are born in rural areas with very few incentives have chances of increased rate of deaths. On the other hand, the children with the availability of better incentives have lesser chances to be threatened by Birth weight and prenatal visits Rate.
