You cannot restrict the values and "comply to a gaussian distribtion." However, if you mean a standard normal distribution (i.e., you are limiting the range to within four sigma of the mean) then the damage done will be minimal. CDF[NormalDistribution[m, s], m + 4 s] - CDF[NormalDistribution[m, s], m - 4 s] // FullSimplify erf(2 Sqrt[2]) % // N 0.999937 filteredData = Select[RandomReal[NormalDistribution[], {1000}], -4 < # < 4 &]; Length[data] 1000 Bob Hanlon ---- "elvisgraceland at gmail.com" <elvisgraceland at gmail.com> wrote: ============= Dear experts, Is it possible to generate random numbers b/w any two limits (say b/w -4 & 4 ) which would comply to a gaussian distribution ?
