摘要
本文简要介绍了L_P估计的有关内容，并详细推导了单位权方差因子的计算公式。LS估计中单位权方差因子计算公式只是本公式的一个特例。
The includings of L, estimation are briefly introduced in this paper, and the equation tocalculate unit weight variance factor is deduced in detail. The equation calculating unitweight variance factor in LS estimation is just a special example of this equation.
