Re: Regression assumptions

A violation of the normality assumption of the residuals is not as serious as heteroscedasticity and autocorrelation. A moderate departure from normality does not impair the conclusion when the data set is large (Bhattacharyya and Johnson 1997 p. 359). Greene (2012 pp. 64-67) states that a normal di...

Re: Regression assumptions

OK. But in order to justify this assertion to other people we need to elaborate on theoretical grounds, right? Any suggestions?

Re: Regression assumptions

Is sounds much easier to apply a remedy. Does EView has one?

Re: Regression assumptions

Thanks a lot for prompt ansewr! I need some explaining:

C) What is considered to be a small sample? Can it be quantified?
D) What is considered to be extremely non-normal? Can it be quantified?

And I still need a justification on why it is not important unless C or D come into place.

Regression assumptions

Hello to everybody Berry (1993) states a number of assumptions to be satisfied in regression analysis(underneath). My concern is assumption 8: the residuals are normally distributed. In many cases they are not. My questions are: A) What is the remedy to non-normal distribution of the residuals in EV...

Re: sample in a group

Thank you! Some adjustment is needed. I have individual files of daily returns for companies and the daily returns of the market as a whole for the same period of time. The name structure for the individual companies is: R_N_companyX_P_ where the component companyX varies from company to company. Th...

Re: sample in a group

Example
group members:
Company1 return 0,01
Company2 return 0,04
Company3 return 0,04
Market return 0,03

need to sample so that companies above market return form a new group, that is company2 and company3

sample in a group

Use Eviews 7.

I have a group consisting of daily returns of individual stocks. Need a sample that shows only daily returns of individual stocks above market return and make a new group with these observations. How can this be done? A spesific solution would be greatly appreciated.

Re: Non-integer power

One solution is using a loglinear transformation of the Hansen-Jagannathan bound but this would imply the assumption that the correlation of the stochastic discount factor and the volatility of consumption growth is equal to minus 1.
