stdev | Computes the standard deviation | Architecture library

I have two questions:

1. I wanna replace redCandlesCounter with barssince, because it looks better. The thing is when I do that: if (barssince(not isCandleGreen and close > middleBand and open < upperBand) > 2 and isLong) kinda breaks the logic by selling on the next candle, which is not what I want. By the way, the tests were done on GTO/USDT (Binance) 30m interval, pictures are at 30 Mar '21 18:30.

1. A sexier way to replace isCandleGreen = close > open?

I am using the following code to make a small example of a function I intend to use on a big data set. I calculate statistical features incrementally for each ID in which the unit is month.

I have a custom function that creates a scatterplot:

My goal is to have draw 500 sample points, take its mean, and then do 6000 times from a distribution. Basically:

Take sample lengths ranging from N = 1 to 500. For each sample length, draw 6000 samples and estimate the mean from each of the samples. Calculate the standard deviation from these means for each sample length, and show graphically that the decrease in standard deviation corresponds to a square root reduction.

I am trying to do this on a gamma distribution, but all of my standard deviations are coming out as zero... and I'm not sure why.

This is the program so far:

corr is the correlation coeficient value, meaning I have 3 correlation values and std_mev are standard deviation value meaning I also have 3 standard deviation values. I want my code to check if the conditions in the code below are met and if they are met it should execute the statement that is true and compute the induc values as shown in the code. Unfortunately no error or even an execution is being performed to produce the induc values please assist, I have a attached a picture to show this. the code is below:

this morning I received a mal containing, among other things, a file with the extension .wsf, on which I inadvertently clicked.

I immediately realized that I had made a mistake ... but too late :( Can you tell me if it is malicious code?

Here is the code:

I'm trying to calculate ZSCORE basen on a measure created in DAX.

Measure would be:

I'm trying to use the train_test_split function by providing the labels array that is a 2-d array for stratifying, with only 0 or 1 values (i.e. [0,0], [0,1], [1,0] or [1,1] are the four possible labels). I cannot rename labels (e.g. to 1,2,3,4 for instance) for code compatibility reasons.

Hereafter the code of the function where train_test_split is used

I have a dataset upon which I would like to implement the Naïve Bayes algorithm but it is triggering an error on line 107; str_column_to_float(dataset, i) as follows; "could not convert string to float:''" I thought it was because of the headers for the various columns but even after I removed them and run the code, it is still giving me the same error. Any help will very much be appreciated. The link to the dataset is as follows; [Dataset][1] The code is below
