The ema function returns a vector of the EMA of the previous N points. In your code, N is 10, and since your input vector test has 11 elements, it's possible to calculate 2 moving averages. You can think of a moving average as a "window" of size N (10,...

To apply a filter to an aggregate formula you use the HAVING keyword: SELECT SUM(SaleAmount) AS SaleAmount, CompanyName FROM [Sales Totals by Amount] GROUP BY CompanyName HAVING sum(SaleAmount) > ( Select AVG(SaleAmount) as SaleAmount FROM [Sales Totals by Amount] ) ...

If you have a matrix you need to sum the elements of the nested lists. You also need to convert those to integers: total = sum(int(i) for sublist in outerlist for i in sublist) length = sum(len(sublist) for sublist in outerlist) average = total / length This assumes you wanted...

import java.util.Scanner; public class ArrAvg { public static void main(String[] args) { int a[] = {1,2,3,4,5,6,7,8,9,10}; int occur = 0; double sum = 0; double avg = 0; for (int i = 0; i < a.length; i++) { if (a[i] == 4) { occur++; } } for (int i =...

The best way to do this would be to use window functions: SELECT OrganizationCode, CreatedDate , AVG(TotalCost) OVER ( PARTITION BY CreatedDate ) AS [Daily Average] , COUNT(*) OVER ( PARTITION BY CreatedDate ) AS [Daily Amount] FROM #TempLocalOrg; The above assumes that dates are rounded or truncated to the...

You need to initialize total to zero: int total = 0; It is currently uninitialised and could be anything. A couple of other things to watch out for: Your median calculation relies on the vector being sorted If there is an even number of values the median is usually defined...

Here is a couple of approaches: -With base R: aggregate(length~name,d,mean) # name length # 1 a 5.0 # 2 b 8.5 # 3 c 7.0 -With the dplyr package (definitely worth spending time to explore) library(dplyr) d %>% group_by(name) %>% summarize(avg=mean(length)) # Source: local data frame [3 x 2] #...
