Fig. 5From: Water level prediction using long short-term memory neural network model for a lowland river: a case study on the Tisza River, Central EuropeGeneral quantile–quantile (QQ) plots of the 7-day ahead forecasts obtained using the LSTM model on the test set over different forecasting horizons (1‒7 days). The gray band indicates the required precision of a given day’s forecast, and the red linear fit indicates the average deviation of the predicted data from the observed dataBack to article page
