Splet28. jun. 2024 · Most of the common statistical models (t-test, correlation, ANOVA; chi-square, etc.) are special cases of linear models or a very close approximation. This beautiful simplicity means that there is less to learn. In particular, it all comes down to y = a ⋅ x + b which most students know from highschool. Splet20. feb. 2024 · The simplest regression model is a straight line. It has the mathematical form: y = a 0 + a 1 x 1. where x 1 is the input to the system, a 0 is the y-intercept of the line, a 1 is the slope, and y is the output value the model predicts.

SpletCheck different kind of models. Another model might be better to explain your data (for example, non-linear regression, etc). You would still have to check that the assumptions of this "new model" are not violated. Your data may not contain enough covariates (dependent variables) to explain the response (outcome).

Then we can substitute the intercept and slope provided. To find the x -intercept, we set the output to zero and solve for the input. 0= −400t+3500 t= 3500 400 t= 8.75 0 = − 400 t + 3500 t = 3500 400 t = 8.75. The x -intercept is 8.75 weeks.
