            If you already installed Selenium by pip install selenium or by any other way and still see that error I guess you are missing a system PATH set to Python or Selenium folder in your machine.
            So just add those folders locations to you machine PATH as described here or any other place.

            fbProphet does not use any of other models. It is a model. Once again, I link an article where you can check details and bring out the most important part, the math.

            The prophet model is using three important features: trend, seasonality, and holidays. It is not necessary to use all of them. And now the formula is the following (citing the article):

            Prophet fits several linear and non-linear functions of time as components. In its simplest form;

            Can I calculate the confidence bound of a Prophet model that would contain a certain value?
            Asked 2021-May-03 at 23:28

            can I use the y-hat variance, the bounds, and the point estimate from the forecast data frame to calculate the confidence level that would contain a given value?

            I've seen that I can change my interval level prior to fitting but programmatically that feels like a LOT of expensive trial and error. Is there a way to estimate the confidence bound using only the information from the model parameters and the forecast data frame?

            I'm unable to reproduce your error, but I believe I know why the fit is failing. The data you are trying to fit are closing stock prices for >500 stocks. When plotted using data_to_use.plot.scatter(x='ds', y='y', s=0.01), you get:

            I believe the fit is failing because it is simply struggling to converge to a reasonable solution as mentioned in this pystan discourse thread. When I naively try to fit this data, it doesn't fail but instead gives a nearly horizontal line prediction near y = 100 with very large error bars.

            Depending on what you're trying to do, I'd suggest either picking one stock by Name, for example:

            Name Multiple Ranges - Using Data in Two Columns
            Asked 2021-Feb-21 at 20:29

            I searched for this with no luck. Any help is appreciated.

            Data Set

            I have a fairly tall dataset (roughly between 1,000 and 5,000 rows) with two columns; one for category and the other for values. The data varies; there might be 10 categories, maybe 100, or any other number:

            Column A Column B Category 1 Value 1 Category 1 Value 2 Category 1 Value 3 Category 2 Value 4 Category 2 Value 5 Category 2 Value 6 Category 3 Value 7 Category 3 Value 8 Category 3 Value 9 Category 3 Value 10

            etc.

            Objective

            I would like to create ranges based on the values in Column A that only include the values in Column B, using the value of Column A as the name of the range.

            So for example:

            • Range Name = "Category 1" ; Range Values { Value 1, Value 2, Value 3}
            • Range Name = "Category 2" ; Range Values { Value 4, Value 5, Value 6}
            • Range Name = "Category 3" ; Range Values { Value 7, Value 8, Value 9, Value 10}
            • etc.
            Things Attempted

            I've tried a number of things, but I'm such a VBA novice that I can't tell what is an effective way to approach this solution and fear I keep making wrong turns in the approach.

            I thought perhaps trying to find the next distinct value in Column A might be a good idea paired with the offset function, but I can't get much further than simply creating and naming the range of categories to look through in Column A. I'm sure this isn't necessary, but I am definitely not a VBA expert.

            As per my comment, I'm not sure whether what you're doing is the best way of doing things, and since you can't have spaces in the names of named variables, if your categories are actually going to be words and some could have spaces, you're setting up a lot of heartache processing exceptions. That aside, if it's really what you need, you weren't that far off, but you can't keep track of the start and end of each range with one variable. The code below will do what you've asked for:

            Answered 2021-Feb-10 at 12:30

            I believe understanding the procedure a bit more will help. When you Modeltime Resample is designed to take your model's specification and refit it repeatedly to resampled data.

            What is resampling?

            It's the idea that we want to test how our models would have performed given that the models were trained on subsets of the data. This is useful in understanding our confidence in the models and how it changes especially with time series (temporal) data. Resampling require re-training and re-evaluating the model specification on each resample (train/test 1, train/test 2, ..., train/test N).

            What is a model specification?
            • It's the parameters you've specified and model type (modeling function and engine)
            • It's not the "Fitted Model" (meaning it doesn't make predictions with your model)
            How does the internal Modeltime Resample process work?
            1. Modeltime Resample uses the fit_resamples() function from tune and applies to each model in a modeltime table containing one or more models.

            2. The refitting process ignores your "fitted model", but copies the parameters selected and the modeling specification to repeated fit (train) new models to the resamples.

            3. The result is how your model would have performed if fitted on different samples of the data. You can display the results using the plotting and table utilities.

            Facebook Prophet Multivariate Forecasting "Found NaN in column"
            Asked 2021-Jan-19 at 13:44

            I have a multivariate five year dataset, with five other features in addition to y. I have a train test split, where the training set is the first 4 years. I want it to predict the 5th year, so I can compare the results with the actual 5th year data.

            I make the future dataframe with make_future_dataframe(periods=365). I pandas.concat the future and train DFs (as pandas.merge cuts off the blank 5th year) future_regressors = pandas.concat([future, train[['f1', 'f2', 'f3', 'f4', 'f5']]], axis=1). Prophet however wants the 5 regressors to have values in the 5th year (which it expresses by complaining about the NaNs from the beginning of the 5th year), but the data doest exist in the training set.

            Found the answer on this SO post, specifically:

            Note that the additional variables should have values for your future (test) data. If you don't have them, you could start by predicting add1 and add2 with univariate timeseries, and then predict y with add_regressor and the predicted add1 and add2 as future values of the additional variables.
