skekurtest

Hypotheses test concerning the univariate skewness and kurtosis.

Description

This function deals with the univariate hypotheses test concerning skewness and kurtosis.

It needs to input data vector, direction of tests (1 = one-tailed; 2 = two-tailed)[default = 2], and significance level (default = 0.05).Immediately it outputs, for an one-tailed hypothesis whether or not the skewness to left or rigth were met. As well as whether or not the kurtosis to left or rigth were met.In case of a two-tailed hypothesis, whether or not the skewness and kurtosis were met.

nice one. you might want to be careful with the name of the output of the routine.

Shame on you.

My Dear Ji Cling,
 
Regularly I visit this FEX site in which excellent contributions for the fast solution of diverse types of problems in several disciplines have been given. The accusation that you are causing is very delicate. I do not know you. Neither the authors. We known them only by the references given in their author page. Only what I believe is in the quality of ethics of each one of them and ours. We are serious people dedicated to our work in the most diverse specialties. To be certain what you say. Then not alone this author does cheating but also all the others. Even you, that in principle, I think you are not signing with your true name. Finally, or really the community are honestly dawnloaded the m-files or finally someone are doing a very bad play. This because there exists a lack of control on this.

Best Wishes.

Mike

Great idea!
However, I'm having difficulties using the file in R2010b:

>> skekurtest(AlphaTotal,1)
??? Error using ==> histc
Edge vector must be monotonically non-decreasing.

Error in ==> hist at 92
    nn = histc(y,edges,1);

Error in ==> skekurtest at 115
[c,v]=hist(X,X); %record of data in a frequency table form

AlphaTotal is a 460x1 matrix.

Do you have an idea on how to fix this? I would really appreciate your help! :)

hey Thorsten, did you ever find a solution to the
??? Error using ==> histc
Edge vector must be monotonically non-decreasing.

Error in ==> hist at 92
    nn = histc(y,edges,1);

problem?

thanks,Alex
