getWV: Test Equality of Curves with Homoscedastic or Heteroscedastic...

In curvetest: The package will formally test two curves represented by discrete data sets to be statistically equal or not when the errors of the two curves were assumed either equal or not using the tube formula to calculate the tail probabilities.

Description

This is a utility function.

Usage

getWV(x, myx, kernel = kernel, alpha = NULL, bw = NULL, bc = "simple", getit =TRUE)

Arguments

x	The x values in the data set that defines the curve.
myx	The x-values in the x-domain that will be used to calculate the curve values.
kernel	Kernel functions.
alpha	Smoothing parameter.
bw	Bandwidth. If both alpha and bw are specified, hh will be used instead.
bc	Boundary correction method.
getit	Logical, tell the algorithm whether to calculate or to laod the file to speed up calculation.

Details

This function will accomplish the bulk load of calculations in the algorithm. If getit=TRUE, the algorithm will run the calculation and save the result in somewhere for future load. Otherwise, it will just load the saved output. This will save a lot of time when do a simulation for a large number of iterations.

Value

The function will return the calculated k0, delta,delta2, degree of freedon vv, etc that will be used in the curve fit and test step.
