QUESTION
I am using spgwr::ggwr()
to fit generalized geographically weighted regression with Poisson model and log-link function. The results provide local coefficient estimates, but i am missing how to get their standard errors (or t statistics) to compute pseudo p-values.
Below is a toy example using SpatialEpi::NYleukemia
dataset:
ANSWER
Answered 2021-Jun-06 at 15:55You may obtain standard errors from local coefficients running the function GWmodel::ggwr.basic
. Function spgwr::ggwr()
returns coefficients but no standard errors.
QUESTION
I have a data frame which is individual-level data of people in a country. In the said data frame I have information on county or municipality of residence, sex, age, race and cancer status.

Answered 2020-Feb-02 at 22:04We can use max.col
on the negative transformed df_dist
after setting the values in columns that are 0 for 'is_metro' to 'Inf'. The max.col
will get the index of the maximum value (by changing it to negative -
, it gives the index of min value) and then extract the values with a row/column index
