  2. Annuity - Wikipedia

    en.wikipedia.org/wiki/Annuity

    Examples of annuities are regular deposits to a savings account, monthly home mortgage payments, monthly insurance payments and pension payments. Annuities can be classified by the frequency of payment dates. The payments (deposits) may be made weekly, monthly, quarterly, yearly, or at any other regular interval of time.

  3. Pearson correlation coefficient - Wikipedia

    en.wikipedia.org/wiki/Pearson_correlation...

    Pearson's correlation coefficient is the covariance of the two variables divided by the product of their standard deviations. The form of the definition involves a "product moment", that is, the mean (the first moment about the origin) of the product of the mean-adjusted random variables; hence the modifier product-moment in the name.

  4. Actuarial notation - Wikipedia

    en.wikipedia.org/wiki/Actuarial_notation

    Actuarial notation is a shorthand method to allow actuaries to record mathematical formulas that deal with interest rates and life tables. Traditional notation uses a halo system, where symbols are placed as superscript or subscript before or after the main letter. Example notation using the halo system can be seen below.

    One particle: N particles: One dimension ^ = ^ + = + ^ = = ^ + (,,) = = + (,,) where the position of particle n is x n. = + = = +. (,) = /.There is a further restriction — the solution must not grow at infinity, so that it has either a finite L 2-norm (if it is a bound state) or a slowly diverging norm (if it is part of a continuum): [1] ‖ ‖ = | |.

  6. Peroxide - Wikipedia

    en.wikipedia.org/wiki/Peroxide

    The characteristic structure of any regular peroxide is the oxygen-oxygen covalent single bond, which connects the two main atoms together. In the event that the molecule has no chemical substituents, the peroxide group will have a [-2] net charge.

  7. Valuation of options - Wikipedia

    en.wikipedia.org/wiki/Valuation_of_options

    The valuation itself combines (1) a model of the behavior of the underlying price with (2) a mathematical method which returns the premium as a function of the assumed behavior. The models in (1) range from the (prototypical) Black–Scholes model for equities, to the Heath–Jarrow–Morton framework for interest rates, to the Heston model ...

  8. Present value - Wikipedia

    en.wikipedia.org/wiki/Present_value

    Equivalently C is the periodic loan repayment for a loan of PV extending over n periods at interest rate, i. The formula is valid (for positive n, i) for ni≤3. For completeness, for ni≥3 the approximation is . The formula can, under some circumstances, reduce the calculation to one of mental arithmetic alone.

  9. Organic peroxides - Wikipedia

    en.wikipedia.org/wiki/Organic_peroxides

    For example, the loss of blue color in leuco-methylene blue is selective for hydrogen peroxide. [21] Quantitative analysis of hydroperoxides can be performed using potentiometric titration with lithium aluminium hydride. [22] Another way to evaluate the content of peracids and peroxides is the volumetric titration with alkoxides such as sodium ...
