bandwidth.grid {extremefit} | R Documentation |
Create either a geometric or an uniform grid of bandwidths between two values
bandwidth.grid(hmin, hmax, length = 20, type = "geometric")
hmin |
the minimum value of the grid. |
hmax |
the maximum value of the grid. |
length |
the length of the grid. |
type |
the type of grid, either geometric or uniform. |
The geometric grid is defined by:
grid(l) = hmin * exp( ( log(hmax)-log(hmin) ) / (length -1) ) ^ l , l = 0 , ... , (length -1)
Return a geometric or uniform grid of size length between hmin and hmax.
hmin <- 0.05 hmax <- 0.2 length <- 20 (h.geometric <- bandwidth.grid(hmin, hmax, length, type = "geometric")) (h.uniform <- bandwidth.grid(hmin, hmax, length, type = "uniform"))
