R 如何解释仿真模型中的MAPE值？
我计算了mape如下，得到的mape值为0.9576856R 如何解释仿真模型中的MAPE值？,r,statistics,R,Statistics,我计算了mape如下，得到的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$predicted_wait_time) 如何解释mape值 Actual wait time
mape <- function(actual,pred){
mape <- mean(abs((actual - pred)/actual))
return (mape)
}
d1 <- d1[which(d1$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.
