高斯分布抽样

使用高斯分布进行采样，确定各区间的采样数量

def generate_list_gussian(list_range,list_num,gussian_sigma=1,gussian_step=0.2):
    for i in range(0,int(list_range)):
        print i,'##'
        gussian_prop=stats.norm(0,gussian_sigma).cdf(gussian_step*(i+1))-stats.norm(0,gussian_sigma).cdf(gussian_step*i)
        print int(gussian_prop*list_num)


generate_list_gussian(10,10000)
