How to compute generalized mean? Mean : Mean also known as the average, and it is computed by dividing the summation of the observations by the total count. There are three basic types of mean and they are also part of the central location measures; AM (Arithmetic Mean) HM (Harmonic ...
Mathematicians and researchers often have large sets of data collected on a certain problem, such as the household income of American families. To summarize the data, they often use the mean, median and mode. Mean The mean is the average of all numbers in a data set. For example, in the...
The problem is I do not know how to balance my data in the right way in order to compute accurately the precision, recall, accuracy and f1-score for the multiclass case. So I tried the following approaches: First: wclf = SVC(kernel='linear', C= 1, class_weight={1...
The assumed mean takes a ballpark guess at the mean, then uses math to calculate a number close to the mean. It is assumed because it is not an actual mean calculation. It is important to remember that the only time you should use assumed mean is if you have very small amounts of da...
The mean, median and mode are measures of central tendency and may also be referred to collectively as types of averages. The term “mean” in the context of statistics refers specifically to the arithmetic mean since there are other types of means, such as the geometric mean or harmonic me...
The median is the midpoint value in a set, the number that half of the values lie above and half of the values lie below. It is usually close to the average (mean) but is not the same thing. Variance Formula If you eyeball a set of 25 scores like the ones above and see almost ...

How can one prove the statement $$\lim_{x\to 0}\frac{\sin x}x=1$$ without using the Taylor series of $\sin$, $\cos$ and $\tan$? Best would be a geometrical solution. This is homework. In my math class, we are about to prove that $\sin$ is continuous. We found out, tha...
To compute the standard deviation, we compute the difference between each monthly return and the average monthly return (there are 36 such data points for our duration). Take the square of this difference and compute the average. Then take the square root of that average. This will always be...
Averages provide a way to compare a range of values, or to show how one value relates to a group of values. Averages are often used to show trends in statistics. The average is also referred to as the mean. An integer is any positive or negative whole number, as well as zero. Numb...
