如何在仿真模型中解释MAPE值？

Question

我已如下计算mape，并且得到mape值为0.9576856。

mape <- function(actual,pred){
  mape <- mean(abs((actual - pred)/actual))
  return (mape)
}
d1 <- d1[which(d1$actual_wait_time!=0),]
mape(d1$actual_wait_time ,d1$predicted_wait_time)

Actual wait time summary:

summary(d1$actual_wait_time)
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
   0.00   25.00   48.00   55.36   77.00  551.00 

Predicted wait time summary:

summary(d1$predicted_wait_time)
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
   0.00    6.00   24.00   31.37   44.00  444.00
