Sorry, I'm a bit lost. Don't you have this tab (see attached).

Effect Sizes / Re: Negative Mean?

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.

Same here, are the extra statistic tabs in the paid version?

Installation / Operation / Internationalisation problems ...
« Last post by Dev on 13 June, 2012, 11:01:21 PM »
From the FAQ

1. If you are in what Microsoft calls an International Setting (e.g., France, Germany, etc), then you may get the following error when trying to run the software:
    Runtime Error - 13: Type mismatch
    This means that you do not have the English (United States) settings in your Regional Settings. To fix this, change Regional Settings to English (United States) under My Computer / Control Panel / Regional Settings. Once
     finished using the programme, however, you might want to change back to your own region again.

2.  Another problem may occur in countries where a comma is used instead of a decimal place. Here's what to do:

    Under Windows XP / Vista / Win 7 in English slight variations around the following works: Access the 'Regional and Language Options' under the Control Panel. Then under 'Regional Options' you
    select 'Customise' and then change the decimal symbol to a "." instead of a ",". Accept the changes and try the programme again (some machines may need a reboot).

    In German, a colleague advised us of the following: in the German version is the order 'Regional and Language Options' (in German ?Zeit, Sprache, Region?) under the Control Panel (in German ?Systemsteuerung?).
    Then under 'Regional Options' (in German ?Tastaturen und Eingabemethoden ?ndern?, English ?alter keyboard and input method?) you select 'customise' (in German ?Format?, English ?format?),
    then ?further settings? (in German ?Weitere Einstellungen?) and then change the decimal symbol to a "." instead of a ",". Accept the alteration and it works without any problems. - Thank you Dirk!

Effect Sizes / Re: Equation for repeated measures effect size

My pleasure. I've just looked at the picture I attached and it's not that clear. It should be:

correlated t-statistic multiplied by Square-root of ((2(1-r))/n).

On a side note: We will be submitting a paper ourselves soon which demonstrates that Hedges' g is a better approximation, under most circumstances, that Dunlap's equation (the one above - which is usually recommended for correlated designs).

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.

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,

Dev
