Hi,  
I’m trying to use the bootstrap function to find the mean and sd of a dataset that I have generated. As an example, the following code gives me the mean, error and bias:  
A = randn(10)  
m = bootstrap(mean,A, BasicSampling(1000))

Output:  
Bootstrap Sampling  
Estimates:  
Var │ Estimate Bias StdError  
│ Float64 Float64 Float64  
─────┼─────────────────────────────────  
1 │ -0.295697 0.00130826 0.293785  
Sampling: BasicSampling  
Samples: 1000  
Data: Vector{Float64}: { 10 }

But I need the distribution of mean values of the 1000 bootstrap samples. Is there any way to get that on Julia?

You are looking for the unfortunately undocumented `Bootstrap.straps` function.

See [Feature to retrieve all sampled results so that a histogram can be obtained · Issue #86 · juliangehring/Bootstrap.jl · GitHub](https://github.com/juliangehring/Bootstrap.jl/issues/86)

Perfect!  
Thanks a lot.
