BIM Level of Accuracy in 95% confidence interval

[Joel]

Hello all,

when comparing two point clouds using the "compute cloud/cloud distance" function, you can have the normally distributed standard deviation calculated afterwards using the "distributions fitting" function.

Is there also a function that calculates the 2Sigma standard deviation within 95% confidence?? For example to calculate the level of accuracy for BIM applications?

Hum, I guess it's not simply twice the standard deviation then?

Thanks you're right.
Maybe i should refresh my statistic knowledge...
