Regression testing is intended to uncover any bug that may have been introduced in the application as a side effect of fixing some other bug. So all the test cases are run. This is different from Unit testing, where we run only unit tests for the unit where we fixed the bug.
Stress testing stresses particular functionality so see where is will break etc. For example a good stress test for MS Word may be to open a file in MS Word and keep writing text to it till it breaks.

A regression test is a test where a previously known bug is tested for after a change. A retest is simply repeating a test.
in general regression model the dependent variable is continuous and independent variable is discrete type. in genral regression model the variables are linearly related. in logistic regression model the response varaible must be categorical type. the relation ship between the response and explonatory variables is non-linear.
the residual is the difference between the observed Y and the estimated regression line(Y), while the error term is the difference between the observed Y and the true regression equation (the expected value of Y). Error term is theoretical concept that can never be observed, but the residual is a real-world value that is calculated for each observation every time a regression is run. The reidual can be thought of as an estimate of the error term, and e could have been denoted as ^e.

diferece between ratio and regression
What is the difference between the population and sample regression functions? Is this a distinction without difference?
Computer Science = software ECE = hardware + software + telecommunication
software engineering is the the management of different phases in SDLC to give a quality product. Software manufacturing refers to the whole process from scratch to end.

There is a big difference. A software engineer will deal only with the machine language withing a computer network. Networkingengineer is an HARDWARE engineer he will apply the software written language to make sure that the network hardware can follow the written machine language

btech engineering is relates to its all parts and fields as-software and harware all . And comp. with IT is complete software field. computer engineering to be a perfect engineer perfect in every field of it.
