The following plots are accompanied by their Pearson product-moment correlation coefficients image credit :.

But notice that the horizontal line has an undefined correlation. We just don't know! Intuitively, there's no way we can determine the correlation from equafion available data. So we have zero on the denominator. Unsurprisingly, this will not be phylogeny simple meaning either. In this answer I have only considered the case of simple linear regression, where the response depends on one explanatory variable.

But the argument also applies to multiple regression, where there are several explanatory variables. The response how to determine a linear regression equation describe fails to meet at least criterion 5, so the General Linear Model does not apply to this example. Sign up to join this community.

This model is a perfectly fine regression model and the data are perfectly fine for applying a regression model. Model residuals are conditionally independent. Model residuals are distributed with conditional mean zero. Model aa have constant conditional variance. Model residuals are conditionally normal in distribution.

Gauss—Markov theorem still applies even if residuals aren't normal, for instance, though lack of normality can have other impacts on interpretation of results t tests, confidence intervals etc. This is an extreme example of the fact that data recorded to a finite accuracy can't have strictly normal errors. How would you tackle it then?

In fact, I don't think 5 ever applies to real data! Sure, regression can be performed with all kinds of residual distributions, and 5 is not related to the calculation of RSS. As Silverfish says, 5 relates to the evaluation and interpretation of estimated quantities like p-values and confidence limits, quantities that render the General Linear Model useful for inference and not merely regression. It isn't needed in any explanation, as shown how to determine a linear regression equation the other answers.
