I'm not sure if it's statistics related but I came over this in my stats related computing assignment.

Does $R^+$ (looks like R to the power of plus) mean all positive real numbers? Does it include 0?

    $\begingroup$ To clarify (though the explicit answer can be found among in many of the links I get from my linked search above); usually it means positive reals rather than non-negative reals. $\endgroup$ – Glen_b Oct 9 '13 at 5:50

It depends. You should ask your course instructor to clarify the definition.

I met the two definitions from different sources. One is non-negative real numbers. Another is positive numbers.
