creating dummy with loop command
Hi Dimitri,
Thanks for help,
i knew that way that you have suggested but in fact my case is a little bit complicated than this,
therefore, i am writing a better explanation now,
my model is trying to see the effect of eco-innovative industries on total output, thats why i am trying to estimate by-industry regression:
the model is
lnQ~lnC+lnM+lnL+lnE+eco_inno+inno+(sum)ind_3d

question about the degrees of freedom
Dear R users,
I think i have a simple question which i want to explain by an example;
i have several 2-digit industry codes that i want to use for conducting by-industry analysis but i think there is a problem with the degrees of freedom!
for example, when i do my analysis without any 2-digit industry code, i got the following summary (i have 146574 observations in total):

question about the degrees of freedom
Thank you for your advice, ill try to be more explicit now, i wasnt in the first mail because i thought it is a simple question to answer,

transparency?
dear R wizards:
I am getting to play more and more with fun fonts (irony warning). I
now know that I can safely use my TeXtext encoding with the postscript
device, but not with the pdf device. Unfortunately, I believe that the
postscript device does not support translucent colors---or is there a
version parameter (like the version="1.4" that I need with the pdf
device) that would

Best mail encryption solution for per-user
Hai,
Do you have advice about Dovecot plugins for mail encryption:
https://wiki2.dovecot.org/Plugins/MailCrypt
https://0xacab.org/riseuplabs/trees
I like NaCL based encryption but the MailCrypt plugin is better
because it's maintained by Dovecot developers (is this correct?)
Hard to understand MailCrypt docs so may I ask, may I provide per user
encryption? I don't like global

Power of test
What would be the R formulae for a two-sided test?
I have a formula for a one-sided test:
powertest <- function(a,m0,m1,n,s){
t1 = -qnorm(1-a)
num = abs(m0-m1) * sqrt(n)
t2 = num/s
pow = pnorm(t1 + t2)
}
Would you pls let me know if you know of?
Thank you,

Hello All,
I could use a recommendation if anyone has a moment. I have the T100P but I have not gotten my service yet. I want to have at least 12 lines of digital voice with DID.

Thanx for your response,
yeah, i know i didnst specified the indexes
when i wrote the 2nd mail, in fact in the 1st mail i wrote already that

reason why i didnt write in fact since the issue is not to estimate the
model but to get the marginal effect,
anyway, i figured out that predict(), doesnt work for panel data...
and
