Fitting a half-normal distribution?

[#1]

Hi,

Does anyone know if its possible to fit a half-normal distribution in the "Analyse" -> "Distribution" function.

Or if there might be a simple way of fitting a half-normal distribution?

Thanks.

You want to fit half of a normal distribution to a set of data or you want to create a half normal probability plot of effects?

Hi Dave,

The first, I want to fit half a normal distribution to a set of data. Actually exactly like when you use "Continues Fit" in the "Distribution" function under the "Analyse" tab.
