Arrow with a letter d on top of it?

[hassman]

What does it mean? Is it simply just the limiting distribution? like x ----> d on top N(1,1)

means that X tends to normal distribution as sample size increases?

 

[LeonhardEuler]

It means x http://en.wikipedia.org/wiki/Convergence_of_random_variables#Convergence_in_distribution" to N(1,1)
