Exponential Function

In general (e.g. in STATISTICA 2D Graphs), you can fit to data an exponential function of the form:

y = b*exp(-q*x)

where the constants b and q are determined by the least squares method. In Nonlinear Estimation, options are provided to fit linear functions of multiple (predictor) variables inside the exponent expression, i.e.:

 y = exp(a+b1*x1+...+bk*xk).
