In aeronautics, the rate of climb (RoC) is an aircraft's vertical speed, that is the positive or negative rate of altitude change with respect to time. [1] In most ICAO member countries, even in otherwise metric countries, this is usually expressed in feet per minute (ft/min); elsewhere, it is commonly expressed in metres per second (m/s).
In financial technical analysis, momentum (MTM) and rate of change (ROC) are simple indicators showing the difference between today's closing price and the close N days ago. . Momentum is the absolute difference in stock, commod
Snap, [6] or jounce, [2] is the fourth derivative of the position vector with respect to time, or the rate of change of the jerk with respect to time. [4] Equivalently, it is the second derivative of acceleration or the third derivative of velocity, and is defined by any of the following equivalent expressions: = ȷ = = =.
The ROC space and plots of the four prediction examples. The ROC space for a "better" and "worse" classifier. The contingency table can derive several evaluation "metrics" (see infobox). To draw a ROC curve, only the true positive rate (TPR) and false positive rate (FPR) are needed (as functions of some classifier parameter).
Rate of change may refer to: Rate of change (mathematics), either average rate of change or instantaneous rate of change Instantaneous rate of change, rate of change ...
Rate of profit; Rate of return (RoR), also known as 'rate of profit' or sometimes just 'return', is the ratio of money gained or lost (whether realized or unrealized) on an investment relative to the amount of money invested; Return on assets (RoA) Return on brand (ROB) Return on capital employed (ROCE) Return on capital (RoC) Return on equity ...
This subset of reactions is then used by the second AutoChem preprocessor program RoC (rate of change) to generate the time derivatives, Jacobian, and Hessian. Once the two preprocessor programs have run to completion all the Fortran 90 code has been generated that is necessary for modeling and assimilating the kinetic processes.
The ROC curve is created by plotting the true positive rate (TPR) against the false positive rate (FPR) at various threshold settings. An example of ROC curve and the area under the curve (AUC). The area under the ROC curve (AUC) [1] [2] is often used to summarize in a single number the diagnostic ability of the classifier. The AUC is simply ...
