Calculate the coefficients for a focal ("moving window") OLS regression model.
## S4 method for signature 'SpatRaster'
focalReg(x, w=3, na.rm=TRUE,
fillvalue=NA, filename="", ...)
x |
SpatRaster with at least two layers. The first is the "Y" (dependent) variable and the remainder are the "X" (independent) variables |
w |
window. The window can be defined as one (for a square) or two numbers (row, col); or with an odd-sized weights matrix. See the Details section in |

fillvalue |
numeric. The value of the cells in the virtual rows and columns outside of the raster |
