I am quite new to statistical analysis, so this question might seem a bit obvious. My problem is the following. I have performed a simple linear regression between two sets of values without uncertainty, resulting in a regression equation of the form =ax+b.y=ax+ I have calculated the...
In statistics, the parameters of a linear mathematical model can be determined from experimental data using a method called linear regression. This method estimates the parameters of an equation of the form y = mx + b (the standard equation for a line) using experimental data. However, as wit...

Understand what simple linear regression is. Learn how to find the regression line by hand or a graphing calculator using the linear regression equation. Related to this Question What is the standard error of measurement? What is the standard error and what does it measure?
Classic OLS SEs can be generalized so that some assumptions, namely that the regression model errors are independent, can be relaxed. The foundation for this is thesandwich estimator2 (2) Let’s first understand how the above equation relates to eq. 1, the classic OLS parameter variance: One...
Standard Error of Estimation:There are several equations and mechanisms for determining the standard error of estimation in linear regression. If we know the mean square of the error, we can apply the equation: {eq}\displaystyle S_e = \sqrt{MS_E} {/eq}Answer and Explanation: ...

The linear regression between two variables is referred to as correlation. The standard error is the spread of the sampling distribution. For any regression equation, a smaller standard error is a good sign of the model.Answer and Explanation: ...
