[Garaad Awal]

Will be posting qpadm of Somalis and Horners here. Others are welcome to post and discuss.

Qpdam is very unreliable, if I change the reference the whole results significantly changes. I kept the target and the source the same and I got a minimum Dinka value of 24% and a Maximum Dinka value of 46%? All these by only changing the reference values? Unless your a pro Qpdam player otherwise its a waste of time. I advice anyone to not waste their money and subscribe to Qpdam.

It’s a steep learning curve but I’m getting the hang of it. I’ve also been in this pop genetic game for awhile so I do know which models make sense historically and which models to attempt. If the std value is huge then there is something wrong with your references or your model is terrible. You also shouldn’t take models that pass but have a P-value very close to 0.05 seriously. It’s not a waste of time or else academics wouldn’t be using it.

Managed to get a significantly higher P for myself with slightly lowering std error. Used only the super high coverage PN samples as sources.

I agree, it will take some time to fully understand this tool. It's only suitable for someone with your level of knowledge. What I meant is that beginners might misinterpret the results, because the tool is very sensitive and requires someone with expertise to eliminate errors and use the right level of source and reference otherwise the model will be terrible and unreliable.

What references did you use?

Your range levels are way off what’s allowed

Any model above +-3% figure should be discarded. Swap out your reference pops with this

Tested it with my Kit

Scoring 5% looks reasonable imo but the best Cushitic proxy is actually the Kenya_Somali sample which gives the highest P values. I tend to also prefer modern Yemenites as an Arabian proxy.

That range looks abnormal. Try using this reference list.

I tried your reference but kept my sources. The P-Value is very good but not as good as the last run I did but the std error dropped from 6 to 5% which is the lowest I have ever gotten. The Arabian did inflate tho

@Fez I will run the Eritreans, Afars & Beta Israel and compare to both yours and mine. I feel like with your references the Arabian might be inflated. Also I will try running the Somali samples individually to see if it works for some of them

Got my best result so far, this is the closest to 1.0 p-value I’ve been so far
