Best starting points for systematic reviews and meta-analysis
A colleague asked for advice about writing a systematic review, for a team that had never written one before. Below is a refined version of my advice.First, note that these days there is a systematic…Continue

Know Your Limitations: "Data" and "Big Data" vs. "Statistics" and "Models" and the Necessity of Good Theory
If you are reading this blog, you like numbers. Perhaps you even love them. Even if you are a dedicated qualitative researcher, I’d urge you to continue reading; this blog might be even more valuable…Continue

Role of methodological quality in meta-analysis
1 Reply
For a few years now, I have been doing some work related to the methodological quality (MQ) of meta-analyses and of the studies they integrate, which have both shown an increasing presence in…Continue

Post No Bills (here unless it is about meta-analysis generally; but do so in specific items to groups)
The forum is a little like a blank wall that is irresistible: It just seems to attract comments. So, let me start with a little humor:…Continue

As I write, the first day of 2014 is fading and the new year will quickly become just a fact along the way. The reprieve from emails and demands that the holidays permit will be a distant memory. And big data will grow bigger and bigger still and require more and more help from cool research synthesis procedures and meta-analytic statistics. That's why we are here. I am teaching a graduate seminar this spring on the subject, at the University of Connecticut, and I've asked…

Meta-Analysis: The Original 'Big Data'
I'm winding down after a productive sabbatical leave and of course summer's waning days. I should be working on that new course preparation (yikes, I'm teaching in a week!), but I wanted to say something about trends in recent months (and years) connected to Big Data in the media and science.
It strikes me that the original instantiation of big data is meta-analysis. Isn't it the goal of meta-analysis to pool all the relevant data into one…

Mastering Meta-Analysis
Most of what scholars do hinges on having sufficient skill to create meaningful assessments of knowledge and the evidence base that underlies it. Meta-analysis is a skill set you can develop if you work at it with enough deliberative practice. How much deliberate practice does it take?…

Our Communal Collective
It's sunny as I write you from my home office in mid-September, where I work at home during my sabbatical leave. As you probably know, sabbaticals are a periodic break from the regular hum-drum of academic life in order to focus more concertedly on other goals, mainly scholarly.
Popular belief has it that "sabbatical" is just another word for "vacation," but it is not true, well at least not for me: It is true that I am teaching no courses until next fall (and trying hard not to think…

Sophie Reyer said… Good Day,
How is everything with you, I picked interest on you after going through your short profile and deemed it necessary to write you immediately. I have something very vital to disclose to you, but I found it difficult to express myself here, since it's a public site.Could you please get back to me on:(sophiereyer1@onet.pl) for the full details.
Have a nice day
My best regards.
Sophie.

I guess it has been a long time! I'm up to my usual tricks--you know me. To tell you would take more time and space than I have here. We should keep in touch a little better. How are you?

Thanks, Blair! I'm delighted that you've set up this community. I hope you don't mind, but I want to connect some of my other colleagues/students.
Take care,
Bill

Is there a place to download either version of dstat? Looks like I'm back at my meta-analytic ways.
Great site! Nat

Great site! I just learned about it this morning. All is well here.... just at that point in the semester when I'm swamped!

Wolfgang Viechtbauer said… - Hi Blair,
I haven't had that much time to poke around, but this site looks like it could be a really useful resource for anybody who is conducting or about to start conducting meta-analyses. I'll do my best to add some information about meta-analysis software (and the metafor package) when I have some time.
Best,
Wolfgang
