Hello, I produced a histogram for a single continuous variable (minimum value=0, mean=31, SD=14) using PROC SGPLOT. I included a normal density curve for the distribution, as well as a normal density curve for the same continuous variable from a standard population for comparison (lowest possible value=0, mean=43, SD=26.0). Given the lowest possible value is 0, I am not sure why the left tail of my normal curves extend past 0, and do not intersect at 0. Any insight would be very much appreciated! Thank you:)
