Calculates statistical intervals of the best nonlinear fit for a data set (X, Y).

	data specifies static data that the user-defined function needs at run time.
	f(x,a) is a reference to the VI that implements the fitting model. Use the VI template located at labview\vi.lib\gmath\NumericalOptimization\LM model function and gradient.vit to create the VI from a template.
	confidence level specifies the level of certainty for the confidence interval. The default is 0.95, which means the probability that the best fit falls between Lower Bound and Upper Bound is 95%. confidence level must be greater than 0 and less than 1.
	Y specifies the array of dependent values. The number of input points must be greater than zero and greater than the number of best fit parameters. The number of elements in Y must be equal to the number of elements in X.
	X specifies the array of independent values. The number of input points must be greater than zero and greater than the number of best fit parameters. The number of elements in X must be equal to the number of elements in Y.
	Weight is the array of weights for the observations Y. Weight must be the same size as Y. If Weight is unwired, this VI sets all elements of Weight to 1. If an element in Weight is less than 0, this VI uses the absolute value of the element.
	best fit parameters specifies the array of parameters that minimizes the weighted mean squared error between the solution vector and the observed y-values.
	error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE. code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source specifies the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
	Upper Bound returns the upper bound of the confidence interval.
	Lower Bound returns the lower bound of the confidence interval.
	delta best fit parameters returns the confidence radius of best fit parameters.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error. status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
