In trying to probe this, I'm unable to even get the code to run due to an error occurring within the conquer
package.
library(jtools)
library(quantreg)
library(data.table)
n = 2500
dat = data.table(
x = runif(min = 0, max = 1, n = n),
y = factor(sample(c('A','B'), size = 100, replace = TRUE))
)
dat[, z := x * 0.6 + 0.3 * (y == 'B') + rnorm(n = n, mean = 0, sd = 1)]
qr <- quantreg::rq(z ~ x + y, data=dat, tau = 0.5, method = 'conquer')
#> Error in match.arg(kernel) : 'arg' must be of length 1
This is true for all examples I can test fitting rq
models. Could be an issue with my configuration, but for now I'm reticent to try to fix the underlying bug with jtools
when I can't actually produce an rq
model without p-values to test my work.
Thanks Jacob, I'm getting that error now too. Evidently it's not a very mature technique (and I had to ditch it for other reasons).
In
summ.rq()
, there is a point where it is assumed that there is a p column in the fourth column of the coefficients. For the recently implemented "conquer" algorithm, this is not the case.It can be worked around with a check at line 166 of summ_rq.R:
Just calling the p-value 1, so it doesn't highlight anything, I'm sure that it's not the best solution.
