Ah, the stochastic error term and the residual are like happy little clouds in our painting. The stochastic error term represents the random variability in our data that we can't explain, while the residual is the difference between the observed value and the predicted value by our model. Both are important in understanding and improving our models, just like adding details to our beautiful landscape.
In regression analysis, the stochastic error term represents the unobserved factors that influence the dependent variable and account for the randomness in the data. It reflects the differences between the actual values and the predicted values generated by the model. The residual, on the other hand, is the difference between the observed values and the predicted values from the regression model for the specific sample used in the analysis. While the stochastic error term is theoretical and pertains to the entire population, the residual is empirical and pertains only to the data at hand.
There is no difference.

The difference between low percent error and high percent error is one is low and the other is high
Bias is systematic error. Random error is not.
A stochastic error indicates an error that is random between measurements. Stochastics typically occur through the sum of many random errors.
Mathematical model is exact in nature.it has Beta zero and Beta one and no stochastic or disturbance variables. Econometric model represents omitted variable, error in measurement and stochastic variables.

It would help to know the standard error of the difference between what elements.
A Stochastic error term is a term that is added to a regression equation to introduce all of the variation in Y that cannot be explained by the included Xs. It is, in effect, a symbol of the econometrician's ignorance or inability to model all the movements of the dependent variable.
they are the same thing.
Regression analysis is based on the assumption that the dependent variable is distributed according some function of the independent variables together with independent identically distributed random errors. If the error terms were not stochastic then some of the properties of the regression analysis are not valid.
The difference between an actual correct view and a displaced visual parallax error
Half of the difference between the two positions is called the "index error".
