Please suggest..

After factor analysis, my scale factorized in to 3 factors such as knowledge creation, Knowledge sharing and knowledge application. Three of these are my dependent variables.

Now If i have to compute these three factor items under one name such as knowledge management process.. Do I have to take their Sum ,their Mean or sum of their Z Score?

Please suggest

I have two histograms, looking at the proportion of cases meeting a criteria in London and in England. When comparing histograms, say you a 5-10 group, isn't their a risk that those included are all 10 in London and are spread out evenly nationally? and so when you compare the two 5-10 bars with each other their contents may not be like-for-like.

What's an acceptable level of skewness? I found the SKEW function in Excel but I'm not that clear on the interpretation.

Can anyone help? ]]> Statistics skewif http://www.talkstats.com/showthread.php/43676-Comparing-histograms http://www.talkstats.com/showthread.php/43660-Testin-Additivity?goto=newpost Fri, 17 May 2013 10:58:36 GMT Hello everyone, does anyone know how you can test for additivity in a parametric regression model?

does anyone know how you can test for additivity in a parametric regression model?
For instance, if you have a regression model with two factors, can you just fit another regression model including an interaction term and then base your decision on its corresponding p-value? Or is it better to compare both regression models based on some criterion?

thanks in advance,
