R i = the return on the stock in state i, and E[R] = the expected return on the stock. The standard deviation is calculated as the positive square root of the variance.... Note: var(y) instructs R to calculate the sample variance of Y. In other words it uses n-1 'degrees of freedom', where n is the number of observations in Y.

Find the probability of having four or less correct answers if a student attempts to answer every question at random. Solution Since only one out of five possible answers is correct, the probability of answering a question correctly by random is 1/5=0.2.

**r How to calculate the regression variance for a GLS**

So, firstly, you should calculate the sum of the differences of all data points with the mean. Have a variable called count and set it to the value 0. For that, you loop through the data set with a variable, say i and subtract i every time with the mean.... After you calculate the variance of a set of numbers, you have a value whose units are different from your original measurements. For example, if your original measurements are in inches, their variance is in square inches. This is because you square the deviations before you average them. So the

## How To Find Variance In R

### The usefulness of R 2 is its ability to find the likelihood of future events falling within the predicted outcomes. The idea is that if more samples are added, the coefficient would show the probability of a new point falling on the line.

- Checking VAR_SAMP and VAR_POP in the H2 and PostgreSQL databases and VAR and VARP in Excel we find that in all three cases the sample variance uses n-1. Here is an R example
