UPDATE: Our eighth annual SEM The Musical was held on April 29, 2014. We had three new songs this year, which are shown below. We also performed some songs from previous SEM Musicals (links: 1, 2, 3, 4, 5, 6, 7).
Ivette Noriega, sporting her homemade Daft Punk helmet, and Dr. Reifman perform "Saturated Your Model." You may click on the photo to enlarge it.
Saturated Your Model (example)
Lyrics by Ivette Noriega and Alan Reifman
(May be sung to the tune of “Get Lucky,” Bangalter/de Homem-Christo/Williams/Rodgers)
Performance videos of this song from SEM The Musical 9 and 10.
In the world, of SEM graphs,
All the paths, have beginnings,
It keeps, statisticians spinning (uh-huh),
AMOS will be helping,
(Look)
You've, gone too far,
You’ve linked all, paths there are,
None you’ve left out,
Einstein’s quote, did you flout?
Fit indices are at 1,
Degrees of freedom are none,
You’ve got to know, what you’ve done,
You’ve saturated your model!
Fit indices are at 1,
Degrees of freedom are none,
You’ve got to know, what you’ve done,
You’ve saturated your model!
You’ve saturated your model,
You’ve saturated your model,
You’ve saturated your model,
You’ve saturated your model,
(Instrumental)
S-E-M, has no limits,
Your theory, is depicted,
What is it, you’re testing?
Parsimony says, leave out paths (uh-huh),
You've, gone too far,
You’ve linked all, paths there are,
None you’ve left out,
Einstein’s quote, did you flout?
Fit indices are at 1,
Degrees of freedom are none,
You’ve got to know, what you’ve done,
You’ve saturated your model!
Fit indices are at 1,
Degrees of freedom are none,
You’ve got to know what you’ve done,
You’ve saturated your model!
You’ve saturated your model,
You’ve saturated your model,
You’ve saturated your model,
You’ve saturated your model,
(Voice-synthesizer in background, shown in red)
Fit indices are at 1,
Fit indices are at 1,
Fit indices are at 1,
Fit indices are at 1
Fit indices are at 1 (all of them),
Fit indices are at 1 (it's hard to interpret),
Fit indices are at 1,
Fit indices are at 1,
You’ve saturated your model!
You’ve saturated your model!
You’ve saturated your model!
You’ve saturated your model!
You’ve saturated your model!
You’ve saturated your model!
You’ve saturated your model!
You’ve saturated your model!
You've, gone too far,
You’ve linked all, paths there are,
None you’ve left out,
Einstein’s quote, did you flout?
Fit indices are at 1,
Degrees of freedom are none,
You’ve got to know, what you’ve done,
You’ve saturated your model!
Fit indices are at 1,
Degrees of freedom are none,
You’ve got to know, what you’ve done,
You’ve saturated your model!
You’ve saturated your model!
You’ve saturated your model!
You’ve saturated your model!
You’ve saturated your model!
You’ve saturated your model!
You’ve saturated your model!
You’ve saturated your model!
You’ve saturated your model...

The "Spice Guys," Nicholas (Hairy Spice) and Alan (Veggie Spice), perform "If You Wanna Join My Construct."
If You Wanna Join My Construct (You've Got to Load with My Friends)
Lyrics by Nicholas Johnston and Alan Reifman
May be sung to the tune of “Wannabe” (Spice Girls/Rowe/Stannard)
Performance video of this song from SEM The Musical 9 and 10.
Yo, I’ll tell you what to draw, what you really need to draw,
So, tell me what to draw, what I really need to draw,
I’ll tell you what to draw, what you really need to draw,
So, tell me what to draw, what I really need to draw,
I need a circle, need a box, I need a circle, need a box...,
Really, really, really, really, really, need a box,
If you like my construct, then load significantly,
If you wanna join me, minimize residuality,
Now don't go wasting, iterations,
Get your r's together, we could load just fine,
I’ll tell you what to draw, what you really need to draw,
So, tell me what to draw, what I really need to draw,
I need a circle, need a box, I need a circle, need a box...,
Really, really, really, really, really, need a box,
If you want to join my construct, you gotta load with my friends,
Sharing variation, on that constructs depend,
If you want to join my construct, you have got to show,
High r’s with the other, manifests, you know,
What do you think about that, now that you know the deal?
Say you fit my construct, is your manifest for real?
Got a small residual, I'll give you a try,
If the construct won't account for your variance, then I'll say goodbye,
Yo, I’ll tell you what to draw, what you really need to draw,
So, tell me what to draw, what I really need to draw,
I need a circle, need a box, I need a circle, need a box...,
Really, really, really, really, really, need a box,
If you want to join my construct, you gotta load with my friends,
Sharing variation, on that constructs depend,
If you want to join my construct, you have got to show,
High r’s with the other, manifests, you know,
So here's a story, from r to p,
You wanna get with me, you gotta load significantly,
We got CFA tests in place, and coefficients to taste,
You then see, on your screen, which V loads, on the C,
All your V's, you can see, reflect variance, manifestly,
And if you please, you'll see...
Get your constructs drawn, and run your model now,
Get your constructs drawn, and run your model now,
If you want to join my construct, you gotta load with my friends,
Sharing variation, on that constructs depend,
If you want to join my construct, you have got to show,
High r’s with the other, manifests, you know,
If you want to join my construct...
You gotta, you gotta, you gotta, you gotta, you gotta, load, load, load, load....
Get your constructs drawn and run your model now,
Get your constructs drawn and run your model now (uh, uh, uh, uh...).
Get your constructs drawn and run your model now,
Get your constructs drawn zigazig-ah,
If you want to join my construct...
Non-Exchangeable
Lyrics by Alan Reifman
May be sung to the tune of “Unforgettable” (Irving Gordon; popularized by Nat King Cole)
Non-exchangeable,
Some dyads’ fate,
They’re arrange-able,
By role, or trait,
Such as hetero, spouses or steadies,
Teacher-student pairs, boss and employees,
(Slow) These are studied,
From a distinguishable, view,
But, exchangeable,
Are some, you see,
It’s not absolute,
Who’s A, and B,
Friends, or twins, or old college roommates,
Same-sex spouses, or pairs who go on dates,
More complex stats,
Will be needed, for you...
[Interlude -- Instrumental and vocal improvisation]
Non-exchangeable,
Some dyads’ fate,
They’re arrange-able,
By role, or trait,
Other pairs are, interchangeable,
Their data are, re-arrangeable,
So their, APIM models,
Are harder, to do...
Thanks to Satabdi and Rebecca for the photos!
