Hi list!

I did the following regression:
reg1 <-  glm(alti~sp + ovent + vivent + nuage, family=gaussian, data=meteo1)

I was interested in knowing the effect of the species (sp) in reg1 and so I used the function «effect»:

effect.sp <- effect ("sp", reg1, se=TRUE)

with this output:
sp
      AK       BW       NH       OS       RT       SS 
2.730101 2.885363 2.753774 2.750311 3.084606 2.834390 

If I enter the following command:
    effect.sp$se
I get this output:
            1        253       3100        488        514       6100 
    0.07924610 0.06713200 0.11493178 0.13106639 0.05252749 0.04208334 

My question is:  Do the numbers on the second line of this output represent the standard error?  What do the numbers on the top line represent?

Thank you,
