Arguments

• Y: Numeric vector or data matrix, the estimated c.d.f.
• X: Numeric vector or data matrix, the running variable
• Nl, Nr: Integers, sample sizes to the left and right of cutoff.
• Nlh, Nrh: Integers, sample sizes to the left and right of cutoff, within bandwidth
• hl, hr: Numeric, bandwidth to the left and right of cutoff.
• p: Integer, polynomial order
• s: Integer, higher order derivative estimate
• kernel: String, the kernel function, can be triangular (default), uniform or epanechnikov.
• fitselect: String, the model, can be restricted or unrestricted
• vce: String, specifies the procedure used to compute the variance-covariance matrix estimator. Options are: "plugin" for asymptotic plug-in standard errors. "jackknife" for jackknife standard errors.
• massPoints: Boolean, whether whether point estimates and standard errors

Returns

Returns a data frame for further use.
