public class LinearRegressionTransformer extends net.simplace.sim.io.resources.FWSimResourceTransformer
Calculates linear Regression (slope and intercept) from two double arrays

Inputs and outputs

The transformer takes the field/column names from a resource that act as x and y values.

It outputs

  • the keys of the original resource in same order and same datatypes
  • the slope m (DOUBLE)
  • intercept b (DOUBLE)
  • the mean of x values (DOUBLE)
  • the mean of y values (DOUBLE)
  • r square (DOUBLE)
\[ \begin{eqnarray} \bar{x} & = & \frac{1}{n}\sum_{i=1}^n x_i \\ \bar{y} & = & \frac{1}{n}\sum_{i=1}^n y_i \\ u & = & \frac{1}{n}\sum_{i=1}^n x_i y_i - \bar{x} \bar{y} \\ v & = & \frac{1}{n}\sum_{i=1}^n x_i x_i - \bar{x} \bar{x} \\ m & = & \frac{u}{v} \\ b & = & \bar{y} -m \bar{x} \end{eqnarray} \]
