add_probs.lmerMod {ciTools}  R Documentation 
This function is one of the methods of add_probs
, and is
called automatically when add_probs
is used on a fit
of class lmerMod
.
## S3 method for class 'lmerMod'
add_probs(
df,
fit,
q,
name = NULL,
yhatName = "pred",
comparison = "<",
type = "parametric",
includeRanef = TRUE,
nSims = 10000,
log_response = FALSE,
...
)
df 
A data frame of new data. 
fit 
An object of class 
q 
A real number. A quantile of the conditional response distribution. 
name 

yhatName 
A string. Name of the vector of predictions. 
comparison 
A character vector of length one. Must be either

type 
A string, either 
includeRanef 
A logical. If 
nSims 
A positive integer. If 
log_response 
A logical. Set to

Additional arguments. 
It is recommended that one perform a parametric bootstrap to
determine these probabilities. To do so, use the option type
= "boot"
.
A dataframe, df
, with predictions and probabilities
attached.
add_ci.lmerMod
for confidence intervals
for lmerMod
objects, add_pi.lmerMod
for
prediction intervals of lmerMod
objects, and
add_quantile.lmerMod
for response quantiles of
lmerMod
objects.

# What is the probability that a new reaction time will be less

add_probs(dat, fit, q = 300)
# What is the probability that a new reaction time will be greater
# than 300? (ignoring the random effects).
