We have a regression equation: I) (restricted form , ) We want to do a Ramsey-Reset test and form the alternative hypothesis that the true functional form of the regression is: II) But in our econometrics class it is said that due to the inclusion of in the alternative form (unrestricted form) we say that this regression can not be estimated and its estimators can not be found. It is said that the reason behind it is multicollinearity and by...

explain what a basis for a vector space is. How does a basis differ from a span of a vector space? What are some characteristics of a basis? Does a vector space have more than one basis? Be sure to do this: A basis B is a subset of the vector space V. The vectors in B are linearly independent and span V.(Most of you got this.) A spanning set S is a subset of V such that all vectors...
