Prediction data frame for polr
Get predictions with standard errors into data frame for use with geom_smooth
## S3 method for class 'polr' predictdf( model, xseq, se, level, data, method, formula, method.args, weight, n_boot = 200 )
model |
object returned from polr |
xseq |
sequence of x values for which to compute the smooth |
se |
if TRUE then confidence intervals are returned |
level |
confidence level for confidence intervals |
data |
data to fit |
method |
only works for method MASS::polr |
formula |
formula to fit |
method.args |
arguments to pass to method |
weight |
weights to use for method |
n_boot |
number of bootstraps to perform for confidence interval calculation, default is 200 |
predictdf.polr is used by xgx_geom_smooth when method = "polr"
to calculate confidence intervals via bootstraps.
