marginal effects of mlogit in R

Question

I am new to R, and I don\'t understand yet completely the logic of its calculations...

I cannot overcome my problem with the help from previous posts either.

Answer 1

You could use colMeans

  op <- options(scipen= 100, digits=2)
  colMeans(mldata[,3:11], na.rm=TRUE)
   #  CHINN           DEBT            ERA           INFL          MONEY 
   #  -0.27         115.25           0.20          33.66          74.66 
   #OPENNESS       RESERVES           RGDP           RSVS 
   #  92.06 18809465124.14         136.56          18.81 
  options(op)

or summarise_each from dplyr

library(dplyr)
mldata %>%
summarise_each(funs(round(mean(., na.rm=TRUE),2)), CHINN:RSVS)
# CHINN   DEBT ERA  INFL MONEY OPENNESS    RESERVES   RGDP  RSVS
#1 -0.27 115.25 0.2 33.66 74.66    92.06 18809465124 136.56 18.81
