  Can you provide me an example of resolving regression using Fit.LinearMultiDim.</p>
  
  <pre><code>var xdata = new DenseMatrix(
              new double[,]{{1, 36, 66, 45, 32},
                          {1, 37, 68, 12, 2},
                          {1, 47, 64, 78, 34},
                          {1, 32, 53, 56, 32},
                          {1, 1, 101, 24, 90}});
  
              var ydata = new double[] { 15, 20, 25, 55, 95 };
  
              var y = new DenseVector(ydata);
  
              var p = xdata.QR().Solve(y); // Fit ?
  </code></pre>
  
  <p>Is there any simpler method to achieve this?</p>
