"An approximate answer to the right problem is worth a good deal more
than an exact answer to an approximate problem." - J. W. Tukey
"I like working on applied and theoretical problems at the same time
and one thing nice about statistics is that you can be useful in a
wide variety of areas. So my current applications include
biostatistics and also astrophysical applications. The surprising
thing is that the methods used are similar in both areas." - Bradley
