The current account balance is one of two major measures of a country's foreign trade (the other being the net capital outflow). A current account surplus indicates that the value of a country's net foreign assets (i.e. assets less liabilities) grew over the period in question, and a current account deficit indicates that it shrank. Both ...
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 ...
In banking, a minimum daily balance is the minimum balance that a banking institution requires account holders to have in their accounts each day in order to waive maintenance fees. [1] This is not to be confused with the average daily balance, which is computed as the sum of daily balances in a billing period divided by the number of days. [2]
For the statistic t, with ν degrees of freedom, A(t | ν) is the probability that t would be less than the observed value if the two means were the same (provided that the smaller mean is subtracted from the larger, so that t ≥ 0). It can be easily calculated from the cumulative distribution function F ν (t) of the t distribution:
Small samples are somewhat more likely to underestimate the population standard deviation and have a mean that differs from the true population mean, and the Student t-distribution accounts for the probability of these events with somewhat heavier tails compared to a Gaussian.
The APY is a formula used to calculate the amount of interest earned on an investment or on your account over one year. ... you’ll want to look for an account that doesn’t require a minimum ...
The table shown on the right can be used in a two-sample t-test to estimate the sample sizes of an experimental group and a control group that are of equal size, that is, the total number of individuals in the trial is twice that of the number given, and the desired significance level is 0.05. [4]
In many countries a useful distinction is drawn between the balance of trade and the balance of payments. 'Balance of trade' refers to the trade of both tangible (physical) objects as well as the trade in services – collectively known as exports and imports (in other words, 'visibles plus services') – while the 'balance of payments' also includes transfers of Capital in the form of loans ...
