After creating the descriptive statistics of my sample I want toshow that the mean of a certain variable is statistically significant.For example the mean of var1 is 0,45. Now I want to show that thepositive sign is significant.

. sysuse auto (1978 Automobile Data) . regress mpg

Similarly, quantile regression will test that the median is zero . qreg mpg Iteration 1: WLS sum of weighted deviations = 330.13202 Iteration 1: sum of abs. weighted deviations = 330 Iteration 2: sum of abs. weighted deviations = 328

Raw sum of deviations 328 (about 20)
