Remember they = mx+bformula for a line from grade school? The slope wasm, and the y-intercept wasb, and both were necessary to draw a line. That’s what you’re basically building here too, but most textbooks and programs will write out the predictive equation for regression this way:...

A linear equation looks like an equation (so, there must be an equals sign) whose variables all have an exponent of 1 (in other words, no variable is raised to a higher power, and no variable is under a square root sign). Here are some examples of things to look for: These equation...
If you have a square matrix with a nonzero determinant, then you can always find a unique solution to the matrix equation for any . If, however, the matrix has determinant zero, then there may be either no vector, or an infinite number of vectors which satisfy for a particular . This ...
To show that our analyses also work for complex data, we need to prove an analogous formula for the four basic complex operations. Now \delta will be a tiny complex number bounded in absolute value by a small multiple of \varepsilon. Prove that this is true for complex addition, ...
