A function to get the interpolation methods from a data frame
Usage
getinterp(df)
Arguments
df
a data frame
Value
the interpolation methods
Details
The three types of interpolation method employed in the package lgcp are:
'Majority' The interpolated value corresponds to the value of the covariate occupying
the largest area of the computational cell.
'ArealWeightedMean' The interpolated value corresponds to the mean of all covariate
values contributing to the computational cell weighted by their respective areas.
'ArealWeightedSum' The interpolated value is the sum of all contributing covariates
weighed by the proportion of area with respect to the covariate polygons. For example,
suppose region A has the same area as a computational grid cell and has 500 inhabitants.
If that region occupies half of a computational grid cell, then this interpolation type assigns
250 inhabitants from A to the computational grid cell.
