I am using this function to estimate kernel density in 2D. I am slightly confused by the parameters of this function however.
Here is an example, viewed from directly above, where density is being calculated at each point (O) in the figure. i.e: over very small areas.
I want to change the KDE function parameters so that density is computed over a larger area (for example, the area circled in red). Which parameters do I need to change? I presume it is one (or both) of these:
"n: size of the n by n grid over which the density is computed (default 2^8)"
OR:
"MIN_XY, MAX_XY: limits of the bounding box over which the density is computed". The default limits are computed as:
MAX = max(data,[],1); MIN = min(data,[],1); Range = MAX-MIN; MAX_XY = MAX+Range/4; MIN_XY = MIN-Range/4;
Thanks very much.
