QUESTION
I have a system where I'm using the consensus opinion of weighted votes to predict a binary outcome.
Since elections are topical we can use it as an example. Say I do an analysis on various pollsters over the years and assign them a weighted vote based on how accurate they were. Pollster Skyler ends up with a vote weight of 3 and Pollster Oakely was twice as accurate and ends up with a vote weight of 6. In CGP Grey fashion (a youtuber who sometimes talks about election mechanics) Skyler predicts that the Tiger candidate will win the open city council seat and Oakley predicts that the SnowLepoard candidate will win it. In this example, the projected winner, based on total weighted votes, would be SnowLepoard with a majority weighted vote percent of (6/9) 0.66667. The actual outcome of any given election would of course vary, but generally, if the weights are good, we'd expect the win probability of a given candidate to increases as the majority weighted vote percent increases and, likewise, if the majority percent is 50% for the election to be a real tossup.
With that example in mind, I'm trying to do a logistic regression on a dataset where the only independent variable is the majority weighted vote percent. I've tried a couple of different methods and while both generally agreed that win probability increases as majority weighted vote percent increases, they disagree as to how much and neither really respects the idea that a 50/50 majority weighted vote percent indicates a true 50/50 probability.
The blue line is the logistic regression done through seaborn and the green dots are the logistic regression done through sklearn. Code below. I dont think that the underlying mechanics of a logistic regression change from one library to another so clearly if they're producing different outputs for the same input, my setup is wrong.
- Why are these two libraries producing different regressions?
- How can I force the regression, for either library, to treat a weighted vote majority of 0.5 as a 50% win probability? I can probably just fill in a mass of dummy data to force the conclusion but I feel like theres got to be a more elegant way.

in sklearn does a penalized regression, you can get more details in the help page, whereas seaborn uses statsmodels
to perform the fit, which is not penalized.
Setting the penalty to none in sklearn would give you the same results:

I am totaly new to the cloud in any way. I started some weeks ago with the Azure cloud and we setting up a project using many different products of Azure. At the moment we think about setting up the project on a way that we are not trapped by Microsoft and are able to switch to GCP or AWS. For most products we use I have found similar ones in the other Clouds but I wonder if there is somthing like Azure Data Factory in AWS or CGP? I could not find something in my first google research.
Best and thanks for your help

QUESTION
I'm using a C library which has a struct called dataSet which is used throughout the library. I can declare the struct in my C++ code and pass it to the methods in the C library and it works fine, but I don't know how to access items from this struct in C++ as I get read file access violation. I'm not sure if I should be using the extern command somehow.
main.cpp:
...ANSWER
Answered 2020-Jun-17 at 15:35I want to be able to simply do trainingData->numInputs in my main.cpp file, but I'm not sure if this is possible.
The library has been designed in such a way, as to hide the definition of dataSet
, and thereby prevent access to numInputs
and other members.
Technically, you can access the member, simply by defining the same class as is defined in cgp.c. The definition must match exactly. Otherwise the program will violate One Definition Rule, and be ill-formed (no diagnostic required). As such, this can easily break if the library is later modified. I recommend to avoid this.

QUESTION
I'd like to calculate % of stocks above rolling mean, therefore, I need to group the data by 'Date' and want to keep the 'Date' column. Percentages are calculated correctly, however, instead of actual dates I'm getting 'NaN' values. The 'Date' column is not the data frame index.
...ANSWER
Answered 2020-Jan-09 at 16:02You have to remove the 'Date'
from the [ ], you are already grouping by it. And don't drop the index, Date
is your new index in your returning dataframe and you want to keep it

So I have a query for a report that never finishes. I've allowed it to run for upwards of 20+ mins without completing. Here is the query:
...ANSWER
Answered 2019-Aug-27 at 22:43Since you say you can query the view I suggest selecting your view into a temp table prior to performing the query. This will simplify the query plan, allowing you to inspect it. And may hopefully speed it up.
I note in your original query you are filtering you main table against @Start and @End in the join condition. I don't think you want to do that. I think it should be in the where clause.
Also you can probably pre-filter the temp table so long as you can work out which records may be required (I couldn't because you compare to 3 different dates).
