Sleeping again...

So I'm finally sleeping somewhat peacefully again...

Now my problem is not being able to

 get up at 6am to go to the gym...

But I think I am still catching up to last week's 

horrible, horrible lack of sleep. 

I have, since, found comfort in my humidifier 

which makes a fantastic monotone noise at night 

(and drowns out noisy roommate phone talking issues)

:) 

So, I'm a happy, well-slept bee!!!

But.

I need help for a question in my stats class...

What does this equation mean:

 

y = βο+λ22y+βx+ε

???

Ok.

No need to answer...

I think you get the point ;)
