Questions tagged [smoothing]

Smoothing related to statistical programing solutions in which a signal is filtered to create an approximating function that attempts to capture important patterns in the data, while leaving out noise, or for visual clarity to see general trends.

In scientific software for statistical computing and graphics, function smooth.spline implements a smoothing spline; function ksmooth implements a kernel estimator; function loess implements LOESS.

Is there a way to plot a curve of best fit without function? Python

I need to plot a smooth curve of best fit but all the methods I've found use scipy.optimize.curve_fit(), and this requires knowing the function relating x and y. Is there a simpler way to do it for basic scatter plots? What Im trying to get the…

why is only 60 fps really smooth in cocos2d?

It has probably been asked before, but I can't find it anywhere... In videoland, 24 fps and anything above is smooth. Cocos2d seems to be smooth only when its 60 fps or maybe a bit less. Anything between 30 and 50 is certainly not smooth, the fps…
