stata面板数据的固定效应回归结果如下：

Fixed-effects (within) regression               Number of obs      =      1492
Group variable: company                         Number of groups   =       373
R-sq:  within  = 0.2329                         Obs per group: min =         4
between = 0.0086                                        avg =       4.0
overall = 0.1406                                        max =         4
F(4,1115)          =     84.62
corr(u_i, Xb)  = -0.2457                        Prob > F           =    0.0000

F test that all u_i=0:     F(372, 1115) =     1.18           Prob > F = 0.0231

我该怎么对回归效果进行分析呢？我要得到的是i与s的系数的正负和显著性，然后整体的回归效果怎么看？R-sq: corr(u_i, Xb) 、F(4,1115)、F(372, 1115)等该怎么看？多大为好呢？谢谢高人指点
