Hello all,This might be more of a statistical question than stata but Iwould really appreciate if someone explain me this. I thought Iunderstood normal distribution until I see this. I have a standardnormal distribution table with N(mean=0,standard deviation=1) whichgives me the followingx y |---------------| | -9 1.03e-18 | | -8 5.05e-15 | | -7 9.14e-12 | | -6 6.08e-09 | | -5 1.49e-06 | |---------------| | -4 .0001339 | | -3 .004433 | | -2 .0540047 | | -1 .2420321 | | 0 .3990434 | |---------------| | 1 .2420321 | | 2 .0540047 | | 3 .004433 | | 4 .0001339 | | 5 1.49e-06 | |---------------| | 6 6.08e-09 | | 7 9.14e-12 | | 8 5.05e-15 | | 9 1.03e-18 | | 10 7.70e-23 | +---------------+ summ y Variable | Obs Mean Std.

Am I misunderstandingsomething
