Average treatment effect. The average treatment effect ( ATE) is a measure used to compare treatments (or interventions) in randomized experiments, evaluation of policy interventions, and medical trials. The ATE measures the difference in mean (average) outcomes between units assigned to the treatment and units assigned to the control.
Value at risk. The 5% Value at Risk of a hypothetical profit-and-loss probability density function. Value at risk ( VaR) is a measure of the risk of loss of investment/Capital. It estimates how much a set of investments might lose (with a given probability), given normal market conditions, in a set time period such as a day.
Time value of money. The present value of $1,000, 100 years into the future. Curves represent constant discount rates of 2%, 3%, 5%, and 7%. The time value of money is the widely accepted conjecture that there is greater benefit to receiving a sum of money now rather than an identical sum later. It may be seen as an implication of the later ...
Actual cash value (ACV) ACV is used to determine how much of a payout you will receive for a totaled vehicle. It is determined by the replacement cost of your vehicle minus depreciation, which ...
Net present value. The net present value ( NPV) or net present worth ( NPW) [1] is a way of measuring the value of an asset that has cashflow by adding up the present value of all the future cash flows that asset will generate. The present value of a cash flow depends on the interval of time between now and the cash flow because of the Time ...
Student's t-distribution. Template:Infobox 3386 distribution. In probability and statistics, Student's t distribution (or simply the t distribution) is a continuous probability distribution that generalizes the standard normal distribution. Like the latter, it is symmetric around zero and bell-shaped.
Most frequently, t statistics are used in Student's t-tests, a form of statistical hypothesis testing, and in the computation of certain confidence intervals. The key property of the t statistic is that it is a pivotal quantity – while defined in terms of the sample mean, its sampling distribution does not depend on the population parameters, and thus it can be used regardless of what these ...
Tail value at risk. In financial mathematics, tail value at risk ( TVaR ), also known as tail conditional expectation ( TCE) or conditional tail expectation ( CTE ), is a risk measure associated with the more general value at risk. It quantifies the expected value of the loss given that an event outside a given probability level has occurred.
