Hi,

I'm am trying to script an existing workflow and I am struggling with the last part.

The users have a standard curve of points as part of the data (x = percentage, y=value) and in an external software (Prism, GraphPad) utilise a 6th order polynomial non-linear regression to utilise that curve and then interpolate unknowns from that.

I have my x and y in 2 arrays ready to go.

In trying to recreate this I have been having a try with Math::Polynomial but the interpolate function of that seems to be using the curve data to predict the polynomial needed so I am a little confused.

Does anyone have a hint as to how best to approach this in perl by reading in curve data then reading out the unknowns?

Thanks

If that's not what you want, perhaps you want to use Algorithm::CurveFit or PDL::Fit::Polynomial
