Create either a geometric or an uniform grid of bandwidths between two values
bandwidth.grid(hmin, hmax, length = 20, type = "geometric")
the minimum value of the grid.
the maximum value of the grid.
the length of the grid.
the type of grid, either \(geometric\) or \(uniform\).
Return a geometric or uniform grid of size \(length\) between \(hmin\) and \(hmax\).
The geometric grid is defined by: $$ grid(l) = hmin * exp( ( log(hmax)-log(hmin) ) / (length -1) ) ^ l , l = 0 , ... , (length -1) $$
# NOT RUN { 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")) # }
