what is the difference between a normal distribution and a normal quantile? what's the difference between the normal median and the mean? how to compare models cross validation when a model is cross validated what does the quantile indicate what does the median of a prediction model look like? how does the average of the two models compare which quantile does the model look normal on? can you cross validate an underlying model when the quantile crosses zero how to compare model performance how do you compare two models of a model why is the 0.025 quantile not good in cross validation when the qml is positive the mean is why is 0.025 quantile a confidence interval how to write a distribution for model cross validation why do models cross validate for prediction what model looks normal why should a prediction interval be included what should the confidence interval between models averaging what model is used to compare model performance?
