Hello,

we are searching for a statistical programmer able to translate Matlab-
into R-Code.

The code looks like this:

% Calibration by means of Platt Scaling
classdef CalibratorPlatt<Calibrator

     methods

         % Constructor
         function C = CalibratorPlatt(varargin)
             C = C@Calibrator(varargin{:});
         end

         % Employ a trained calibration model to transform scores (i.e.
         % uncalibrated, continuous class predictions)
         function phat = Calibrate(C, decision_values, model, varargin)

             % Select calibration model to use
             if nargin ==2, model = C.Model; end

             % Compute probability estimates (assuming the LibSVM
             % implementation of Platt Scaling)
             fApB = decision_values*model(1)+model(2);
             phat = zeros(length(decision_values),1);
             idx = fApB>=0;
             phat(idx) = exp(-fApB(idx))./(1+exp(-fApB(idx)));
             phat(~idx) = 1./(1+exp(fApB(~idx)));
         end

         % Construct a calibration model from training data
         function cmodel = BuildModel(C, scores, y)

             [a b]= C.PlattScale(scores, y);
             cmodel = [a b];
         end

We pay 150 RMB and the opportunity for much more projects.
