I think that the function ols_step_best_subset
has limitations. However, there are other ways to get what you are looking for.
The long version:
Okay, I worked with the data you provided, but I did not run into any of the issues you ran into. I thought it may have been due to how few rows of data you had provided. (You provided a lot of information! There just isn't a lot for the model to work with.)
Instead of asking you for more data, since it seemed to be more of a question on the limitations of R, I found a built-in wide dataset. I still didn't run into the issues you ran into.
I used the data dhfr
from the package caret
. It has over 200 variables; I randomly chose 24.
I didn't clean it. I did look at the influential variables and that is likely going to be an issue. I did this as a way to look for multicollinearity which is a really big problem for linear regression. Since that wasn't a problem, I used this data.
QUESTION
I am having fun with pydrake for the region of attraction (RoA) analysis. There is one type of non-linear system involving trigonometry that got me stuck. A similar problem has been posted here.
As Russ points out in that post, there are 2 solutions: 1) shifting to another state-space; 2) using Taylor expansion. I am applying the 2nd approach to the pendulum case to get a feeling. The system dynamics are given in here. Here is what I have:

QUESTION
I am currently facing issues loading data into big query or even creating federated table as the incoming data is delimited by |
pipe symbol with escaped double quotes on fields inside the file
Sample Data (also tried escaping double quote values with double double-quotes i.e ""
on field level)
ANSWER
Answered 2021-Sep-24 at 11:19This is not problem with external table or bigquery, but rather CSV files feature. I had similar once when I uploaded data to table in UI. I have found some sources(BTW which I cannot find right now) that double quotes should be used twice (""
) in CSV file to get such behavior, like using your exaple:

QUESTION
I would like to apply some condition when do the data cleansing in Power BI Power Query.
Only need one date record for each CONSOL ID
ETD (DD/MM/YYYY)
Condition as below:
i.) Date with 'Null' shouldn't be chosen as earliest date when there have available date for that CONSOL ID.
For example: C001 with date '1/1/2021' should be selected as earliest date, but C002 doesn't have other available date. In this case, 'Null' can be selected.
ii.) If the CONSOL ID have few transport mode (SEA or AIR ,RAI,ROA), ONLY priorities on the earliest date of 'SEA' or 'AIR' transport mode.
For example: In C003, even the earliest date is 1/1/2021, but we only focus on the date with transport mode 'SEA' or 'AIR'. So earliest date for C003 is 1/3/2021, while C004 is 1/6/2021.
iii.) If there is only one transport mode (Doesn't matter is RAI or ROA), the earliest date will be selected.
For example: '1/1/2021' for C005 and C006.
