WebHere we are taking a mean over the total number of samples once we calculate the loss (have a look at the code). It’s like multiplying the final result by 1/N where N is the total number of samples. This is standard practice. The function calculates both MSE and MAE but we use those values conditionally. WebApr 25, 2024 · In R, the MLmetrics package provides us the MAPE () function using which we can calculate the MAPE in R. This function has the following syntax: Syntax: MAPE (F t, A t) Parameters: Here, F t: It represent forecasted values A t: It represents actual values Example: R dataframe <- data.frame(At=c(15, 40, 41, 32, 48, 28, 21, 47, 36, 37, 11, 14),
