QUESTION
I ran the following code to impute 10 data frames of 2120 observations.
I expected to obtain a long dataframe of 10 X 2120 = 21200 observations, but I obtained 42400 observations, as if the whole process ran twice. The first 3 columns look like below.
It is not a big problem because I can subset the first half, but I was wondering if someone had an explanation for this. Is there something wrong with my code?
Thanks
...ANSWER
Answered 2021-Oct-15 at 04:16Since the group
values (0:1
) is not used in the loop using lapply
/replicate
would be a good option.
QUESTION
I generated 30 imputed dataframes, which are stored in a list list.of.imputed.dfs
, which is of classes "mild" "list"
. Some of the values in the dataframes need to be changed based on earlier values to create a survival outcome. For instance, if an observation takes on the value 1 for var1
, all subsequent values (e.g., var2
) are 1, otherwise the observations keep their original values. To do this, I used the following code:
ANSWER
Answered 2021-Aug-31 at 17:55You can create a function to modify a dataframe individually, then apply to all the elements in the list.

I'm not sure why I get this error. Below is the entire test file. jQuery object doesn't appear to be initialized. Please help me understand what is the cause of the error.
...ANSWER
Answered 2021-Aug-27 at 11:26I'm no expert in jquery but wasn't their function always exported as $
and not j$
?
EDIT: Thank you @freedomn-m for mentioning it. The root problem was, that the jquery source did not load. For anyone facing a similar problem, I suggest you use the official CDN instead of hosting your own version of jquery. You can find the URL for different versions and bundles here: https://code.jquery.com.
QUESTION
I would like to group my data by state_id
and species
when I run mice::mice
to impute values. I've got it grouped by state_id and results are looking much better than without the bygroup.
mice.impute.bygroup: Groupwise Imputation Function
Edit... improved, working code:
...ANSWER
Answered 2021-Jun-09 at 10:25You shouldn't use mice.impute.bygroup
directly. It is a function that gets called when you specify method["x"] <- "bygroup"
, just like you call mice.impute.norm.predict
with "norm.predict"
(see ?mice.impute.norm.predict
).
Below is some example code on how to use bygroup
.

QUESTION
I have the following data:
...ANSWER
Answered 2021-May-29 at 12:48Answer
You need to supply a formula to densityplot
, otherwise it will plot all variables with > 2 missing values. Since you don't have any variables with 2 > missing values, and since densityplot
doesn't expect that, it produces this cryptic error.
Example that works
