To calculate the recall for a given class, we divide the number of true positives by the prevalence of this class (number of times that the class occurs in the data sample). The class-wise precision and recall values can then be combined into an overall multi-class evaluation score, e.g., using the macro F1 metric. [21]
This is due to put–call parity: a long call plus a short put (a call minus a put) replicates a forward, which has delta equal to 1. If the value of delta for an option is known, one can calculate the value of the delta of the option of the same strike price, underlying and maturity but opposite right by subtracting 1 from a known call delta ...
The sensitivity of the option value to the amount of time to expiry is known as the option's theta. The option value will never be lower than its IV . As seen on the graph, the full call option value ( IV + TV ), at a given time t , is the red line.
Flick Stick is a video game control scheme designed for gyroscopic game controllers.The Flick Stick control scheme is primarily designed for 3D shooter games with the intent of bringing the perceived advantages of mouse aiming to controllers, while addressing shortcomings of traditional first-person shooter controller schemes.
In some literature, the name sensitivity is used for this concept. [1] When the resulting signal is then interpreted by a human operator, as in radar systems, the related term minimum discernible signal may be used. This includes additional factors like clutter and the lifetime of the signal on the radar display.

The Vanna is the sensitivity of the Vega with respect to a change in the spot FX rate: Vanna = ∂ V ∂ S {\displaystyle {\textrm {Vanna}}={\frac {\partial {\mathcal {V}}}{\partial S}}} . Similarly, the Volga is the sensitivity of the Vega with respect to a change of the implied volatility σ {\displaystyle \sigma } :
