what type of model requires data to be of a normal distribution does a vector autoregressive (var) model require data to be of normal distribution? do normal distributions need to be obtained from data what is var data distribution do residuals and data need to be of normal distribution what does a var model require to do what data and residuals must be of a normal distribution for a var model? do residuals of a var model have to be of normal distribution? which is a characteristic of a par model that requires data to have a normal distribution? does a var model require residuals to be of normal distribution? what kind of data is required for a var model do residuals need normal distribution does data and residuals of a var model have to be of normal distribution? do residuals of a var model have to be of normal distribution what is var mean do data and residuals in a var model have to be of normal distribution? what data need to be of normal distribution what is the normal distribution for a vector autoregression what type of data does a var model require does data and residuals of a dar model have to be of normal distribution?
