# 3.5.3.8 Estimation Functions

Name Brief
Kernelwidth Returns the estimated optimal kernel bandwidth for a given vector vX.
Kernel2width Returns the 2D kernel density bandwidths (wx, wy) of X scale and Y scale for dataset (vx, vy) using two different methods.
Gamfit Use Newton-Raphson method to calculate Maximum Likelihood Estimates (MLE) of $\alpha$ (shape) and $\sigma$ (scale) for Gamma distributed dataset.
Wblfit Uses Newton-Raphson method to calculate Maximum Likelihood Estimates (MLE) of $\alpha$ (scale) and $\beta$ (shape) for Weibull distributed dataset $vx$.
