Different definitions in web development like **mean** in Dictionary M.

- Manual Mean Squared Error:
- Meaning average of the squares of all the errors found when comparing predicted values with observed values. Squaring them makes the bigger errors count for more, making Mean Squared Error more popular than mean definition.
- Manual Mode:
- Meaning occurs most often in a sample of data. Like the median, the mode cannot be directly calculated”[stanton] although it’s easy enough to find with a little scripting. For people who work with statistics mean explain.
- Manual Moving Average:
- Meaning average) of time series data (observations equally spaced in time, such as per hour or per day) from several consecutive periods is called the moving average. It is called moving because the average mean what is.
- Manual Mean Absolute Error:
- Meaning Also, MAE. The average error of all predicted values when compared with observed values. See also Mean Squared Error, Root Mean Squared Error mean meaning.
- Manual Markov Chain:
- Meaning working with a series of events (for example, a system being in particular states) to predict the possibility of a certain event based on which other events have happened. The identification of mean abbreviation.
