问个关于precision和accuracy的问题# Computation - 科学计算

现在我有一万个数据，数据有四种形式
a: {x, dx1, dx2},
b: {dx1, dx2},
c: {dx1},
d: {dx2}
其中
x: central value,
dx1: upper error bar,
dx2: lower error bar
现在需要一种数学上合理的方式把他们转成一下形式：
a: x with its precision, which is function of x, dx1, dx2
b: (dx1 + dx2)/2 with its precision, which is function of dx1, dx2
c: 0 with accuracy, which is function of dx1
d: 0 with accuracy, which is function of dx2
Any suggestions how these precisons and accuracies can be determined ?
