Duplicate of Comparing smoothing splines vs loess for smoothing? | |
| Feb 14, 2016 at 20:52 | comment | added | Alexis | @metjush simple logistic regression invokes a specific functional form on the relationship between the DV and a linear combination of the IVs. The point of nonparametric smoothing regressions, such as GAMs and LOWESS, is to make no assumptions about the functional form(s) of the relationship(s) between the DV and IVs. | |

| Nov 7, 2015 at 15:05 | comment | added | pir | Yeah, I've tried logistic regression, LOESS and GAM. The logistic regression doesn't capture the relationship very well. However, I'm more interested in the general case than for my data specifically, which is why I haven't posted plots and data. | |
| Nov 7, 2015 at 14:24 | comment | added | metjush | have you tried fitting a simple logistic regression to it and visualizing the sigmoid? | |
