Is there a formula to calculate left to right current/active? I can scrape together about 1/3 of a formula, but I could use some help!
I can count the number of total values, but I can't imagine how to auto-calculate a current/active streak.

Help me to draw flowchart to find sum of all odf no. from 1 to 100
You can use a loop to keep track of this period and decide if every digit %2 leftovers then it is an odd number
, you can make a variable initialized by zero outside this loop, then you will use it inside the loop to sum all ood numbers produced from the if statement.
I suggest googling the problem on your own, it is more useful for you than my explanation
For my homework, I need to rescale a value that is typically scored 1-7 into a score of 0 and 1. In this case, the values represent political rights, so the lower the score, the less free a country is, and the higher the score the more free it is. My professor hinted that we should consider using a mathematical function that goes like this: newPR = (7-pr)/6; This newPr score would be scored as the score of 0 and 1, with lower scores being represented as 0, and higher scores represented as 1. Any advice on where to start would be amazing!
So the main problem is that I would like to show the average numbers per Week numbers. But I don't know why but it sums up all the averages, and not just average the averages.
My current DAX formula:
Average =
AVERAGEX(
FILTER('Code',Code[Code_name] = "Failure"),
CALCULATE([Time])
)
Where Time is another Measure.
you can see that calculating the average by ID works, but if you collapse the matrix it shows weird numbers per week number.
Any advice?
Consider changing the "Show value as" in the visualization.
By default it is sum, try average of your measure.
In Power BI I am working with a matrix that shows a daily percentage.
When I add a column subtotal this sub total is summing up all the percentages for the selected days.
What I would like is that the Column sub total is showing the average percentage over the selected days.
Picture of the matrix
Thanks a lot for looking at my issue
Depends on how you calculate the percentage itself and on what granularity it exists in your data model, but you might want to play around with the ISFILTERED formula. Not sure what the name of the dimension ranging between 1 and 6 is in your graph, but let's call it day number. You can then do something like:
IF(ISFILTERED(day number), SUM(daily percentage), AVERAGE(daily percentage))
This checks if the daily percentage is filtered by the day number in the visual (matrix) or not. If it is, then it just takes the sum of the percentage (which is the percentage itself for any given day), otherwise it'll calculate the average percentage.
I`ve a 100*100 binary matrix the probability of each pixel given by this relation :
i want to know how to calculate the entropy of this image .
According to the given conditions, the probability for each entry in the matrix can be calculated accordingly.
For example, because s(1,1)=0, s(1,2)=0, s(2,1)=0, then you can calculate P(s(2,2)=0), and P(s(2,2)=1) using the theorem.
After you calculate all the probability for all entries, then you can start to calculate the entropy of this image by calculating the expected value.
Entropy is given by the formula: -Sum(PlogP)
Where log is the base 2 logarithm and P is the probability of the information.
