documentation of class linvpy.Bisquare

[sandylaker]

in the documentation of Bisquare function, there might be a small error in the formula for computing psi, where it should be |x| <= c, and |x| > c rather than |x| <=0 , and |x|>0 in the conditions.

Thanks a lot for reporting this! This is fixed now :)

Enjoy linvpy!
