get_osle_poi_list {expirest} | R Documentation |
Compile information on worst case batches for ordinary shelf life estimation
Description
The function get_osle_poi_list()
prepares a list of points of
intersection (POI) for multiple regression models using the
find_poi()
function.
Usage
get_osle_poi_list(
data,
batch_vbl,
icpt_list,
model_list,
sl,
srch_range,
alpha = 0.05,
xform = c("no", "no"),
shift = c(0, 0),
ivl = "confidence",
ivl_type = "one.sided",
ivl_side = "lower",
...
)
Arguments
data |
A data frame with the columns specified by |
batch_vbl |
A character string that specifies the column in |
icpt_list |
A list of four elements named |
model_list |
A list of regression models of different type. Usually,
it is a list of four elements named |
sl |
A numeric value or a numeric vector of length |
srch_range |
A vector of length |
alpha |
A numeric value between 0 and 1 that specifies the significance
level for the calculation of confidence or prediction intervals. The
default is |
xform |
A vector of two character strings that specifies the
transformation of the response and the time variable. The default is
“no” transformation, i.e. |
shift |
A vector of two values which will be added to the variables
|
ivl |
A character string of either |
ivl_type |
A character string that specifies if a “one sided”
or a “two sided” interval should be calculated, i.e. either
|
ivl_side |
A character string that specifies if the specification
limit, given that the limit has only one side, is an “upper” or a
“lower” bound, i.e. it is specified as either |
... |

Details
The function get_osle_poi_list()
applies the
find_poi()
function (find the “point of intersection”) on
all the models and for each release limit (rl
) provided. With respect
to the latter it differs from the get_poi_list()
function.
Value
A list with the following elements is returned:
all.poi |
A list of the POI values, i.e. a list with one or two list
elements for the side (i.e. |
poi |
A named vector of the worst case POI values of each model, i.e.
named |
wc.icpt |
A named vector of the intercepts of the worst case batches of
each model, i.e. named |
which.wc.batch |
A named vector of the indices of the worst case
batches of each model, i.e. named |
