| Dec 11, 2014 at 18:50 | comment | added | concept3d | @Glen_b as I stated i am new to this and might used the wrong term. What I meant is a population with two gaussian distributions if that doesn't make sense please correct me | |
| Dec 11, 2014 at 16:06 | comment | added | Glen_b | What is a 'bimodal normal distribution'? | |
| Dec 11, 2014 at 15:37 | comment | added | Nick Cox | If the problem is working from a histogram, the origin of data as a time series may be irrelevant. | |
| Dec 11, 2014 at 15:36 | comment | added | Nick Cox | There is no objective detection of bimodality without some criterion for the "strength" of a mode. You need to worry not only about unimodality vs bimodality but bimodality vs multimodality. See e.g. work on Minotte and co-workers on "mode trees" (citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.30.5736) | |

| Dec 11, 2014 at 14:45 | comment | added | gung - Reinstate Monica | What is the nature of the data? Are these single values (eg intensities) over time, or are they histograms? | |
