v33 v34 40 40 * ''LCMS Peaklists'': A peak list contains information about peaks that have been observed over a small set of raw data points and are above a threshold local maximum of the ion count (intensity) in the LCMS spectra.[[BR]] 41 41 * ''BiVariate Kernel Density estimation'': A nonparametric approach of estimating density values using probability density functions, having a 2 dimensional Gaussian kernel or any other kernel. The datapoints that are used in this approach are defined by a pair of variables. [[BR]] 42 * ''LOWESS'': Local regression using weighted linear least squares and a 1^st degree polynomial model. [[BR]]42 * ''LOWESS'': Local regression using weighted linear least squares and a 1^st degree polynomial model. [[BR]] 43 43 * ''PCHIP'': Piecewise Cubic Hermite Interpolating Polynomial; a cubic curve fitting spline function which preserves monotonicity of the data [http://math.lanl.gov/~mac/papers/numerics/H83.pdf] [[BR]] 44 44 * ''Warp2D'': A time alignment method that takes advantage of both dimensions of LCMS data to resolve ambiguities in peak matching.
