From the datetime module's documentation:

%U: Week number of the year (Sunday as the first day of the week) as a zero padded decimal number. All days in a new year preceding the first Sunday are considered to be in week 0.

Edit: My originals answer doesn't work for input 1/2023 and using ISO 8601 date values doesn't work for 1/2021, so I've edited this answer by adding a custom function

Asked 2021-May-31 at 05:03

I'm trying to display stock market data from a third party api in realtime using channels and celery. I'm using celery to get data from the api and channels to receive and send the data to the client.

My issue is that the data isn't rendering in the template and my python and javascript aren't showing any errors so I have no idea what's wrong. Help would be appreciated.

startdate and enddate are strings, not datetime objects. You need to parse these, so something like:

ANSWER

The difference is due to whether the models include a "constant" term or not. For the first case i.e. older statsmodels.tsa.arima_model.ARIMA, it automatically includes a constant term (and no option to turn on/off). If you have a differencing, it also includes it but does so in the differenced domain (otherwise it would be eliminated anyway). So here is its ARIMA(0, 1, 0) model:

What is the difference between "batch size in tf.keras.preprocessing.timeseries_dataset_from_array" and "batch size in model.fit"?

Asked 2021-Apr-28 at 02:54

As you can see from this tutorial (https://www.tensorflow.org/tutorials/structured_data/time_series) I'm working on prediction of time series.

I would like to ask the differences between batch size in tf.keras.preprocessing.timeseries_dataset_from_array as in Section 4 in the tutorial and batch size in model.fit. If these two arguments are the same, then what happens if I also write batch size in model.fit ?

Thank you.

QUESTION

Is there a way to display a fan chart in PowerBI?

Asked 2021-Apr-12 at 16:13

I have the results of a Monte Carlo simulation over 1000 paths along a time series (100 years). I would like to display this in PowerBI as a fan chart. The Line chart visual cannot be used for this, as it is limited to 33 legend items (i.e., 33 paths, in my case). I have tried to use a filter on paths by only displaying the top N paths and the bottom N paths, but the Line chart visual does not allow for both applying a top and and bottom filter.

Is there a PowerBI visual which can achieve what I want?

...

ANSWER

Answered 2021-Apr-12 at 16:13

This might not be exactly what you want but I've approached this sort of thing by defining measures for different percentiles or standard deviations similar in concept to this chart:

You can either define the measures separately and not use the Legend field or else create a parameter table for the various percentiles / standard deviations with a measure that reads in that parameter.
