Effect Sizes / Re: Negative Mean?
« Last post by Dev on 13 January, 2011, 04:01:57 am »
The full version now does everything the old free version did even once the expiry date is hit. Basically, the pro version reverts to the free version after 30 days and also has quite a few extras after that date too. It was designed so that an undergraduate student would not need to pay for it to do their thesis. I was once a student and remember not having money to buy the software I needed to finish my thesis so made sure others wouldn't have this problem.

Daenris,

I don't know what you mean. The ESG does allow negative numbers and the extra stats tab is definitely there. Are you sure you're not confusing terms? Have you got the latest version from here: http://www.clintools.com/download/download.html

As of 11th Jan 2011 the direct link is: http://www.clintools.com/download/ClinTools41-Vista-Support-Locked.exe

Hmm... I downloaded the effect size generator free 2.3 which in parenthesis said current version from here: http://www.clintools.com/victims/resources/software/effectsize/effect_size_generator.html
It appears this is not actually the current version, and it does not include the extra stats tab, and would not allow me to enter a negative sign in the mean box.  I wasn't interested in installing the full package, as I only wanted the Effect Size Generator, so I followed the download link for that. 

The newest version appears to work fine.

Effect Sizes / Negative Mean?
« Last post by daenris on 10 January, 2011, 08:50:55 am »
I just downloaded the Effect Size Generator software to calculate some Cohen's d values.  The program does not allow me to enter a negative sign in the Mean fields, so I can not enter my true group mean values.  Is there a reason why it doesn't allow negative values?  There should be no statistical reason to exclude negative group means from calculation as I have used other Cohen's d calculators successfully with negative values before.

Also, as a side question, is the "Extra Statistics" tab only present on the Pro edition?  I downloaded it to test out the repeated-measures effect size calculations, but the free edition doesn't appear to have an extra statistics tab at all.

Effect Sizes / Re: Equation for repeated measures effect size

Thank you so much!

Hi shireen,

You must have an older version of the software as the new version provides the formula when you click the "do it" button. Download the latest version and just overwrite the old version during the install.

The formula is also attached to here ...

Hope this helps in the review process.

Best,

Effect Sizes / Equation for repeated measures effect size
« Last post by shireen on 05 January, 2011, 01:46:07 pm »
Hello,
A manuscript reviewer has asked for the actual equation used for the within groups estimation of effect size that is provided on the 'extra statistics' tab of the Effect Size Generator. Can someone please provide? Thank you!

Effect Sizes / Working with Meta-analyses
« Last post by Dev on 21 July, 2010, 06:47:19 pm »
I've just had a question that I think others may benefit from seeing the answer. Here's what it said:

Quote
Hi there,
We are interested in purchasing the Effect Size Generator Pro in order to conduct a meta-analysis. We have downloaded the free version and we see that there are a limited number of categories in the database (e.g., study ID, study name, year of study, etc). We are wondering whether we can add more columns to the spreadsheet as we are interested in testing for moderators, or specific elements of the study.
Please let us know if this is possible.
Best,

Here's my answer:

Dear xxx,

There are a few ways of doing what you want but I'm not sure that all of them are easy (maybe even a little cumbersome). If you get a *.met file (let's call it metaanalysis1.met) and enter data you can put many elements from the same study into the file but under the 'include' heading change it to YES or NO (just write over) depending upon whether you want to include that element (i.e., that row) in the meta-analysis. I save the file under a new name before making any changes this way and it means I don't have to change back the yes and no's for each analysis (i.e., I keep a different .met file for each analysis).

If you want to include more columns, however, then you will need to export it as a microsoft access file (e.g., metaanalysis2.mdb) and work with it in Access. However, make sure you don't re-order the columns (you can add columns to the right though) and when it comes to wanting to work with the Effect Size Generator again, you'll need to cut-off those extra columns away and then just rename the file from, say, metaanalysis2.mdb to metaanalysis3.met (simply just rename the file and open it as normal).

Hope this helps,

Dev

Reliable & Clinical Change / Re: RCI
« Last post by Dev on 08 June, 2010, 06:48:19 pm »
Hi Jemma,

Yes, Clintools uses the RCI of Jacobson & Truax. If you open the 'Contents' heading under "Help" on the RCC Generator task bar you will find all the formula used in the programme. Also, the 'About' box (also under "Help") gives a short summary.  ;D

Reliable & Clinical Change / RCI
« Last post by Jemma on 08 June, 2010, 03:10:40 pm »
Hi there

Could someone clarify something for me? There are many different ways of calculating RCI (e.g. Jacobson & Truax - classical approach, or Christensen & Mendoza - taking into account practice effects, and many more) and I was wondering exactly how does ClinTools calculate RCI? Any help would be greatly appreciated!! Is the formula ClinTools uses available?

Thank you kindly
Anita
