| May 24, 2017 at 20:56 | comment | added | Dinidiniz | I will edit with an example. I just want to know why normally we don't include $b_i$ in the models to predict $b_{i+1}$. Is it wrong in someway? | |
| May 24, 2017 at 20:53 | comment | added | Dinidiniz | @MichaelChernick I am not a Statistician, so correct me if I am wrong. When we make the linear regression to understand the constant $\alpha$ or the growth rate, we will have a intercept and slope. In this case the intercept will "include" the error, thus making it expected value be zero. | |
| May 24, 2017 at 20:39 | comment | added | LmnICE | I'm confused: if $b_i$ is an observed value, then it's by definition real life data. Are both $b_i$ and $x_i$ observed variables (i.e. they are measured separately), or is $x_i$ measured then used to calculate $b_i$ in conjunction with some prior knowledge about $\alpha$? | |
| May 24, 2017 at 20:32 | comment | added | Michael R. Chernick | Where is the error term in the linear relationship? | |
| May 24, 2017 at 20:31 | comment | added | Guilherme Marthe | Also from your third equation, a loglog regression seems to make sense. | |
| May 24, 2017 at 20:30 | comment | added | Guilherme Marthe | Can't you create a meaningful series/variable using both x and b? | |
