Answer:
d. It is best measured using the statistic variance inflation factor (VIF).
Explanation:
Multicollinearity is an important issue in multiple regression model, having many independent/ explanatory variables. Multicollinearity is the situation in which two or more independent variables are highly correlated. It is problematic because it increases the standard error of independent variable coefficient & undermines its statistical significance
Variance Inflation Factor [VIF] is a check & corrective measure of multicollinearity.
- VIF as a multicollinearity check : It quantifies the correlation between one explanatory variable with other explanatory variables.VIF = 1 implies there is no multicollinearity (correlation between independent variables); VIF upto 5 implies there is moderate multicollinearity (correlation between independent variables). VIF > 5 implies high multicollinearity (correlation between independent variables)
- VIF as a multicollinearity correction : Calculating
= σ^2 / ![[TSS j (1 - R^2j)]](https://tex.z-dn.net/?f=%5BTSS%20j%20%281%20-%20R%5E2j%29%5D)
; where TSS = total sum of square of variable j , σ^2 = j variance, R^2 j = R^2 from regressing all other independent variable on variable j

Answer: Razor and blade strategy
Explanation:
The Razor Blade Model is a model that is used by companies to deeply discount or give away a core product hoping that the consumers will buy the more expensive and complementary dependent products.
The razor and blades business model is a model whereby one item is sold at a cheaper price or sometimes given for free so as to increase the sales of its complementary good. For example, ink catridges are required for inkjet printers and software and accessories are used for game consoles. So, selling ink catridges at a low rate can lead to more sales for inkjet printers.
<span>North america is about 80% urbanized. this mean that about 75% of north american people live in cities. also the population is very less compared to the land area. May be people would prefer to live in urban areas rather living in rural or forest areas. this condition is helpful in preserving forest and natural resources. the only problem is the quality of living in urban areas will be poor compared to rural areas.</span>
