Python has methods for finding a relationship between data-points and to draw a line of polynomial regression. We will show you how to use these methods instead of going through the mathematic formula.In the example below, we have registered 18 cars as they were passing a certain tollbooth....
The approach described for a 2nd order polynomial regression is essentially linear regression using x^2 as if it were just another independent variable. In this case, the formular for R-square is the same as the formula for R-square for linear regression. ...
Some of the models of the elderly subjects (n1 = 67) were compared with those of the young adult subjects (n2 = 48: 8 subjects at 6 walking speeds) using an adaptation of Student's t-test, following formula (1) (Dagnelie, 1986). The significance level used was < .05. (1)tv=B1...

When I open the structure and click on "LinearModel", I find the supposedly used equation form under "Formula" as LinearPredictor '1 + H2O*CO2 + H2O*P + CO2*P + H2O^2 + CO2^2 + P^2' This formula has 7 terms. However, under "TermNames" 10 terms are listed, and un...
