What is alpha in regression analysis?
Alpha is not generally used in regression analysis. Alpha in statistics is the significance level. If you use a TI 83/84 calculator, an "a" will be used for constants, but do not confuse a for alpha. Some may, in derivation formulas for regression, use alpha as a variable so that is the only item I can think of where alpha could be used in regression analysis. Added: Though not generally relevant when using regression for prediction, the significance level is important when using regression for hypothesis testing. Also, alpha is frequently and incorrectly confused with the constant "a" in the regression equation Y = a + bX where a is the intercept of the regression line and the Y axis. By convention, Greek letters in statistics are sometimes used when referring to a population rather than a sample. But unless you are explicitly referring to a population prediction, and your field of study follows this convention, "alpha" is not the correct term here.

What is the relation between Sample and population regression function?
The sample regression function is a statistical approximation to the population regression function.
What is the importance of correlation and regression analysis in econometrics?
Correlation and regression analysis are crucial in econometrics as they help quantify relationships between economic variables. Correlation measures the strength and direction of a linear relationship, while regression analysis estimates how changes in one variable affect another, allowing for predictions and policy implications. Together, they provide insights into causal relationships, informing economic theories and guiding decision-making. This analytical framework is essential for understanding complex economic phenomena and testing hypotheses.

What is difference between regression testing and retesting?
A regression test is a test where a previously known bug is tested for after a change. A retest is simply repeating a test.
Difference between sample regression and population regression line?
AnswerA sample is a subset of a population. Usually it is impossible to test an entire population so tests are done on a sample of that population. These samples can be selected so that they are representative of the population in which cases the sample will have weights, strata, and clusters. But usually people use random samples. So it's not that the line is different, it's that the line comes from different data. In stats we have formulas that allow a sample to represent a population, if you have the entire population (again unlikely), you wouldn't need to use this sample formulas, only the population formulas.
