These lambda functions do work for other CLS-Stats functions and are not meant to be called directly. They are copied into a workbook as hidden Names along with the functions that need them, so they don’t appear in the Name Manager or in formula autocomplete. Their source code is listed here so that the functions that use them can be inspected in full.
| Function | Description |
|---|---|
BootObs | Reshapes a sample the way the bootstrap functions see it |
BCaPercentiles | BCa confidence interval from a bootstrap distribution |
_PolyFit | Polynomial least-squares fit used by the Poly* functions |
_PolyStretch | Finds where a fitted polynomial stops rising or falling |
_InvLimit | Searches for the confidence limits of an inverse prediction |
_Bisect | Root finding by bisection |
_NumJac | Numerical Jacobian for NLS |
_LMFit | Levenberg-Marquardt iterations for NLS |
FSolveBump | Fleishman coefficients, nudging the kurtosis if needed |
FSolveLadder | Retries FSolve from several starting values |
FSolve | Fleishman power-method coefficients by Newton's method |
FSolveMonotonic | Checks that Fleishman coefficients give a monotonic transformation |
