I want to use MathJax to create an "approximately follows distribution" symbol. It is a tilde with a dot above and a dot below. The closest I get is $\overset{\cdot}{\underset{\cdot}{\sim}}$ but the distance from the bottom dot to the tilde is greater than the distance from the top dot to the tilde.
Thanks,
Jack
Using the lower and raise command should give you a desirable result like this: $\overset{\lower{0.5ex}{\cdot}}{\underset{\raise{1ex}{\cdot}}{\sim}}$.
Hope you find this useful, thanks!
