The classical Linear regression model is one of the important cornerstones of econometrics. It is important to understand the concepts and get hold of important areas.
The estimators that we create through linear regression give us a relationship between the variables. However, performing a regression does not automatically give us a reliable relationship between the variables. In order to create reliable relationships, we must know the properties of the estimators and show that some basic assumptions about the data are true. One must understand that having a good dataset is of enormous importance for applied economic research.
The estimation and hypothesis testing are the twin branches of statistical inference. Based on the OLS, we obtained the sample regression, such as the one shown in Equation.

Best of luck!
Nice 😊😊
👌👌
I didn't understand the part after del values and its calculation.

Ols is minimize of error term or residual term?
Hello Rachit, OLS is minimization of RSS i.e., residual sum of squares. Stay tuned for more such interesting topics. Subscribe and press the bell icon to never miss any update from Economics Pedia. Thank you very much!
Ma'am residual, error term, stochastic error term... etc all r same???
That is an appreciable question. Answering to your question, error term and stochastic error term are same, but error and residual are not same. The difference of it has been explained in the session as well. Thank you for your support and stay tuned to Economics Pedia for new sessions.
What is del?
Please solve this question-
Consider the linear regression model y = - 1.5x + 5.6 + e, where e is a normal random variable with mean 0 and variance O ^ 2 = 4 Determine the mean and standard deviation of when x = 2 and x = 4.5
Where is second order condition for minima
Mam what is the difference between clrm and linear regression model

Mam smjh m toh khair kuch nhi aaya
Pr aapko dekh kr acha boht lga..
