Y=(A0 + A1*X)/(1 + B1*X) When used to fit a standard curve, there is no need to interpret the three parameters. All you care about is that a smooth curve goes near your standard curve points. Prism can easily fit this curve using nonlinear regression. It is not a built-in equa...
I have a set of data that I fitted with a linear fit to create a standard curve and now I'm trying to interpolate unknown x-values for known y-values. I tried using polyval and I'm pretty sure I'm doing it wrong because polyval is returning two numbers instead of three...
the default sampling size will be the raster's cell size. For a TIN, terrain, or LAS dataset, the default sampling will be based on the edges produced by the triangulated surface. If the curve is shorter than the sampling size, the curve will be simplified into a two-point line using ...
Electronic regulation system for gas turbine providing vehicle drive - using switching between standard curves to interpolate intermediate required valuesThe electronic regulation system rapidly switches between a required value curve for a zero regulation disparity and a required value curve for corresp. ...
Performing interpolation on a sequence of time-domain samples is an important (often used) process in DSP, and there are many descriptions of time-domain interpolation (a kind of curve fitting) in the literature and on the Internet. However, there’s a lesser-known scheme used for interpo...
A list of sample vector arrays representing the curve. w: array_like, optional Strictly positive rank-1 array of weights the same length asx[0]. The weights are used in computing the weighted least-squares spline fit. If the errors in thexvalues have standard-deviation given by the vector...
