In statistical process control (SPC), the ¯ and R chart is a type of scheme, popularly known as control chart, used to monitor the mean and range of a normally distributed variables simultaneously, when samples are collected at regular intervals from a business or industrial process. [1]
The value of the AUC is consistent for the same data whether you are calculating the area under the curve for a TOC curve or a ROC curve. The AUC indicates the probability that the diagnosis ranks a randomly chosen observation of Boolean presence higher than a randomly chosen observation of Boolean absence. [ 3 ]
Using the residual income approach, the value of a company's stock can be calculated as the sum of its book value today (i.e. at time ) and the present value of its expected future residual income, discounted at the cost of equity, , resulting in the general formula:
A classification model (classifier or diagnosis [7]) is a mapping of instances between certain classes/groups.Because the classifier or diagnosis result can be an arbitrary real value (continuous output), the classifier boundary between classes must be determined by a threshold value (for instance, to determine whether a person has hypertension based on a blood pressure measure).
Example decision curve analysis graph with two predictors. A decision curve analysis graph is drawn by plotting threshold probability on the horizontal axis and net benefit on the vertical axis, illustrating the trade-offs between benefit (true positives) and harm (false positives) as the threshold probability (preference) is varied across a range of reasonable threshold probabilities.
Discounted cash flow valuation is differentiated from the accounting book value, which is based on the amount paid for the asset. [4] Following the stock market crash of 1929, discounted cash flow analysis gained popularity as a valuation method for stocks.

An example capital allocation line. As illustrated by the article, the slope dictates the amount of return that comes with a certain level of risk. Capital allocation line (CAL) is a graph created by investors to measure the risk of risky and risk-free assets. The graph displays the return to be made by taking on a certain level of risk.
