One way to normalize variables in R is to use the scale function. Here is an example: # create vector set.seed(1234) temp <- rnorm(20, 3, 7) # take a look > mean(temp) [1] 1.245352 > sd(temp) [1] 7.096653 # scale vector tempScaled <- c(scale(temp)) # take a look > m...
but I'm clueless how to calculate the rest. My only idea is to convert the 3d array to a 2d matrix of co-ordinates, multiply by a rotation matrix, and convert back. But I'd rather work directly with the 3d array.Example
Hi, I have a process that I am trying to simulate using sol 701. I would like to calculate the heat generated during the process. I have a few doubts though, a
Convert negative String to long: -1234 Convert a String to Long using Long.valueOf TheLong.valueOfmethod is used to convert a String to a wrappedLong. String number ="1234"; Long convertedNumber = Long.valueOf(number); System.out.println("Convert String to Long: "+ convertedNumber); Str...

Loss Event Frequency (LEF):The probable frequency, given a range of time, that a threat will inflict damage on a resource, generating for example an exfiltration incident. In order to calculate this, it is necessary to take into account the: ...
Now, we can use power powersimu to calculate power for a range of coefficient values assuming different alternative hypotheses and a range of sample sizes. Please note that power powersimu calls the program power_cmd_powersimu rather than powersimu. In the generated table, we can easily see ...
But if what you want is to estimate the average of all the original data, then such a procedure is not usually a good one: a weighted average is needed. And of course it's not possible to give a good answer to your question about the "SD for the summed average" until it is clear...
HOW TO CALCULATE YOUR OPEN RATE Calculating your open rate is easy. Promise. Your open rate = the number of emails opened / the number of emails sent (excluding emails that bounced). Most email providers crunch these numbers for you, but it’s nice to know the math behind how it works...
I want to programmatically [in C] calculate CPU usage % for a given process ID in Linux. How can we get the realtime CPU usage % for a given process? To make it further clear: I should be able to determine the CPU usage for the provided processid or process. The proce...
