RECOGNIZE
STATA
Are you curious? Hahaha..
Hello friends howdy?
Hope that everything gonna be alright, okay..
This time I wanna post
something about recognizing STATA.. Yeah for not wasting time, let’s go to the
point about this statistical analysis software.. In my opinion, I reckon that
this is a very complete software to use fella..
May be, we have ever
heard and used the others such as SPSS, Eviews, Lisrell/Amos (for SEM), R and
etc but I give lots of points for STATA owing to its existence as a combination
of SPSS and Eviews.
STATA has been
facilitated with menu bar just like the other softwares (we just click the menu
and process the data).. Hemmm but in STATA we can use syntaxes friends.. And
don’t worry, it can be learned, right? Hahaha..
We can use our time
efficiently while using STATA because of these given syntaxes.. In example when
we want to change the significance level in our research from 90% to 99%, we
need not open the menu bar and do step by step from the beginning.. We just change
only at the syntax..
This is the example..
See this..
I wanna use this STATA
to do t test for two independent population.. I wanna test whether there is the
similarity in age mean between the genders (men and women). At first I use 90% significance level. There are two
options: We can click the menu bar as usual or we can use the syntax. No matter
because the result is just the same..
For giving you a few Indonesian
vocabularies, I will remain the language be the same with the Indonesian one..
men = laki-laki and women = perempuan.. Okay hahaha.. and age = usia, and the
last gender = jenis kelamin.. This is called transferring language skill..
Hahaha.. In this case, I use the syntax
: ttest usia, by(jen_kel) level(90)
And then when I try to
increase the significance level to 99%,
we just make the syntax: ttest usia, by(jen_kel) level(99),, We just change the
number.. It’s so easy, isn’t it?
We can conclude that
there’s no difference at age means between men (laki-laki) and women
(perempuan)..
Okay, back to my
opinion, STATA is a ombination of SPSS and E views Time Series because we can
do lots of analysis by using STATA. Hemmh, the recommended software, I think
other than SPSS.
Next, we can do
sampling in STATA not only by Simple Random Sampling Assumption, but we can use
Cluster Sampling and Stratified Random Sampling that has a less variance than
Simple Random Sampling..
Okay, that’s just the
introduction of STATA.. Just wait for the next post about STATA tutorial in
analysis,,
I wanna create the others.. Hope this can be useful for you.. Keep
spirit,, Be successful and be blessed :-)
