Cumulative learning is the cognitive process by which we accumulate and improve knowledge and abilities that serve as building blocks for subsequent cognitive development. [1] A primary benefit of such is that it consolidates knowledge one has obtained through experience, and allows the facilitation of further learning through analogical ...
The cumulative property follows quickly by considering the cumulant-generating function: + + = [(+ +)] = ( [] []) = [] + + [] = + + (), so that each cumulant of a sum of independent random variables is the sum of the corresponding cumulants of the addends. That is, when the addends are statistically ...
Cumulative effects, also referred to as cumulative environmental effects and cumulative impacts, can be defined as changes to the environment caused by the combined impact of past, present and future human activities and natural processes. Cumulative effects to the environment are the result of multiple activities whose individual direct ...
Cumulative distribution function for the exponential distribution Cumulative distribution function for the normal distribution. In probability theory and statistics, the cumulative distribution function (CDF) of a real-valued random variable, or just distribution function of , evaluated at , is the probability that will take a value less than or equal to .
Cumulative preferred stock is an equity investment that guarantees dividend payments to shareholders. Unpaid dividends–also referred to as dividends in arrears–accumulate and are then paid out ...
A cumulative song is a song with a simple verse structure modified by progressive addition so that each verse is longer than the verse before. Cumulative songs are popular for group singing, in part because they require relatively little memorization of lyrics , and because remembering the previous verse to concatenate it to form the current ...
A practical benefit of the cumulative system is that it is simple to track with pen and paper when running a large tournament. Of course in the age of computers and smart phones, instead of accumulating points scored against weak players, we could just calculate who had the toughest schedule as with the Solkoff and median systems.
The α-level upper critical value of a probability distribution is the value exceeded with probability , that is, the value such that () =, where is the cumulative distribution function. There are standard notations for the upper critical values of some commonly used distributions in statistics:
