Why Natural log returns (reasons)? with eviews example.

Reasons why we should calculate natural log of a series. Does eviews calculate natural log or not and what is the syntax for each?
"Use a single command" and import data from MS Word ( text file)and MS Excel to STATA.
Переглядів 6596 років тому
Write a single command in STATA and your file is there, very simple. Importing text data from ms word ( a text file) and directly importing data from ms excel ( get rid of error prone copying and pasting) become easy using insheet command.

thankyou so muchhhh
Thank you so much
I cannot do it for pdf, do you know why? I am using exactly the same code but changing for ".pdf"
Thanks

Thank you! It is back now!
thank you!
Thank you very mush!!
Can I use FGLS with Fixed effects at the same time?
THANK YOU!
thank you
Really helpful video. Thank you for uploading this.
You have to mention panel correlation and autocorrelation option in xtgls function at the end, the model you have run at the end is wrong because it is assuming no heteroskedesticity and no autocorrelation is present.
This is great!
Very helpful, thanks!
Finally i got a video this type of problem.Thank you so much for this video.
Thanks man. Other vids start out on calculation as its assumed the unit has been taught. I'm starting from, "What even is that!?"
thanks a lot!!!!
it's a simple thing, but you did save me from the frustration. thanks
Thanks, I struggled a lot, but you solved it.
GREAT!
Sir, I am currently working on a meta analysis. But I am not able to produce association studies of allele contrast (A vs a). Except that all are done but can not understand how to calculate A vs a frequency. If you help me out it will help me a lot. Thanks

Good sir
I don't think there are incorrects as descreibed by other user downstairs. but there are some steps missed, which should have followed the original video, which indeed might mislead the audiences. so i'm gonna give a favor here for those who want to know how to use this method, but get disappointed for the incomplete explanation. before you use this excel method, you should have these understandings: (1) the identity matrix must be a square matrix. (2) we call one matrix a left or right inverse of the other if and only if we get an identity matrix after we multiply the other matrix by the one from left/right side. from (1),(2) we know that the square matrix we get from the last part of the video can't be an inverse of the original non square matrix, because the multiplication of B_3x3 and A_11x3 doesn't make sense and A_11x3 multiplied right by B_3x3 is not a square matrix, not mentioning identity. The inverse matrix of the 11x3 matrix is actually the square matrix we get at the end , multiplied by the transpose of the original 11x3 matrix. (proof) (A^T A)^-1 (A^T A) = I_3 (by associative law) [(A^T A)^-1 A^T] A = I_3 -> [(A^T A)^-1 A^T] is the left inverse of A
Thank you very much for this useful tutorial. I have a question please. Why did you take some variables in the first difference when you have run the FGLS MODEL
to check for autocorrelation.
Thanks 🙏🏻
This does not work for Mac users with Stata/SE16.1. For MacOS users, go to top menu bar, click "STATA/SE" -> Preference -> General Preference -> Command; or I would just do this "STATA/SE" -> Preference -> Manage Preference -> Factory settings, turn everything back to factory settings (normal) If this help you, please hit the like so it stays at the top. It can be annoying when Mac users can;t follow the windows instruction and this could help a lot ;)
I want a continue of this problem so please to send the balance problem to my email id
This was useful for me... 😍
2 method video is uploaded or not
But still the question remains unanswered.. why do we have to computer the rank of a matrix? significance?
If it is a full rank matrix, we can find the inverse.
Thank you very much..
thanks!
thank you sir
Love uuuuuuuuu, really really thanks, Greetings from Colombia. You saved my thesis!!
can i use FGLS in eviews??
Yes, eviews10. I dont know about the earlier versions of Eviews
wanna see an excel application that can find the inverse of non-square matrix using Pseudo inverse method? but it is made for those who speak Indonesian. find here : ua-cam.com/video/s7rMlBAYN5E/v-deo.html

I have seen people using Natural Log "log (p2/p1)", while calculating daily returns of stock/Index for long period data (15-20 years), instead of using '(p2 - p1)/p1'. Could not know very good reason. Is it more accurate to use Natural Log ? Can you make a Video on this in detail for benefit of all of us. Rgds.

Respected sir, linear combination only occurs with columns or row also, if not occurs with row, kindly provide reason.
Thanks
isiodos ... describes what christians or jews ... call it genesis ( another ancient greek word).... the only diffrence is that isiodos .... has more details ... wich means ... jews copied isiodos.... ... in isiodos who 2 floods ... in genesis ...1 flood .... the second flood ... we have deukaleon .... and if read from right to left (as they read the jews) we have noe .... for me is a copy ... with less informations so no snakes ... and other bad pets.... but the down fall of the morality ... down graded ...the first race ...the golden race... i belive in isiodos than genesis ...it is more accurate !
