CATS: Hardware & Software Requirements + other

Postby Steve » 13 Oct 2010, 23:49

Hi, I think that the CATS software may be useful to many people ( including me ),
I only became aware of the CATS software because " one of me mates " asked me what I thought of it.

Now, I am out-of-date in regards the PC I have which runs Windows 98-SE.

After looking around the net and finding no indication of what Operating System was required
to run CATS, I decided ( oh well ) download the software and see what happens.

From that download, in the file " cats-manual.pdf "
it states " ... for Windows versions up to XP " ( Under Heading = RECOMMENDED DIRECTORY STRUCTURE )

Observations / Conclusions ( as regard: CATS vs Windows 98-SE )
a) CATS is a DOS based Application
b) CATS does not ( that I am aware of ) have a Command for exiting it's Application
c) On My Machine, after Launching the " cats.exe " ( via double clicking it in the Directory/Folder it exists in )
Each of the four ( so far attempts ) to terminate the CATS Application
have resulted in System Crash ( requiring Hard Boot )
d) If however, if first a DOS Command Window is Opened and then
from which the CATS Application is Launched Then the, one attempt so far,
termination ( although Windows 98-SE does not like the mechanism ) of the Application
via Clicking the X at the Top-Right of the DOS Window to terminate
the CATS Application, seems to leave the System Stable.

So I correspondingly ask, what is the proper Sequence
to Activate and subsequently Deactivate the CATS Application vs Operating System ?

Unrelated to the above is the following ...
after viewing Tutorial Video 4 .... and progressing in the same " fashion "
on a weekly data set of (approx. ) 3750 data points when subsequently
looking at file " speclog.cvs " there were obsevered in that speclog.cvs file
SEVERAL ( near equal ) Periods with corresponding Bartel's ( statistical ) Scores
of about 0.001 to 0.003.

How then does one go about Selecting Periods when several Bartel's Scores
are VERY LOW and the corresponding Periods are within about 20% of each other ?

It seems to me ( an exterior observer ) that the Utilization of Bartel Scores
must necessarily be Subjective. If you care to answer Please address
Bartel Scores in regard to the Observation that such utilization is Subjective

Meanwhile, I have only played with CATS V1.0 for less than one day
So, When is the Next Version due to be Available ?

Are Subsequent Versions also to be Free ( of cost ) for everyone to use ?

Thank You ( in advance for your detailed response )

Yes, CATS uses a DOS type interface

It can be terminated by ctrl-C.

We have not tested it on older versions of Windows, so it is good to know if it runs. It should be lean enough to.

When several periods are very close, there may be several reasons for that. Or several ways to look at it. This is commonly observed in many physics situations also (fine structure of spectral lines in chemical spectra).

1. A basic frequency may be modulated by slower cycles.

2. The data may need some transformation to remove various forms of bias.

Hi Ray,
Thank you for responding ...

the next time I activate the CATS ( version 1 S/W ) I will attempt
to shut such down via crtl-c

Other: Above I stated

"It seems to me ( an exterior observer ) that the Utilization of Bartel Scores
must necessarily be Subjective. If you care to answer Please address
Bartel Scores in regard to the Observation that such utilization is Subjective"

Ray,
Please address the Validity of Bartels Scores

TIA, Regards,
Steve

I gave a reference to the Bartel's test in another thread.

The test is an obviously good objective test for significance. What is subjective is the significance level. In statistics generally, the level of significance required depends on the person's prior belief about whether something is possible or likely.
