Description Usage Arguments Details Value Author(s) See Also Examples

Extract the fitted values, i.e., the estimated mean values, for an object produced by the geolm function for a specified set of covariates, x. If x is NULL, then then x is taken from object.

1 2	## S3 method for class 'geolm' fitted(object, x, ...)

`object`	An object produced by the `geolm` function.
`x`	A m \times p matrix of covariates for the locations where fitted values are desired. If `NULL`, `object$x` is used.
`...`	Not currently implemented.

If the object has a known mean, i.e., object$mu is not NULL, then the function returns the vector rep(object$mu, m). If object has estimated coefficients, then x %*% object$coeff is returned.

If x is missing, then object$x is used for x. Naturally, ncol(x) must equal length(object$coeff). If x is NULL and object$mu is not NULL, then m is taken to be 1.

The vector of fitted values.
