The United Federation of Teachers ( UFT) is the labor union that represents most teachers in New York City public schools. As of 2005, there were about 118,000 in-service teachers and nearly 30,000 [2] paraprofessional educators in the union, as well as about 54,000 retired members. In October 2007, 28,280 home day care providers voted to join ...
The Šidák correction is derived by assuming that the individual tests are independent. Let the significance threshold for each test be ; then the probability that at least one of the tests is significant under this threshold is (1 - the probability that none of them are significant). Since it is assumed that they are independent, the probability that all of them are not significant is the ...
Systems of government can be divided into two main categories, democratic and non-democratic [8] Democratic. Direct Democracy, Representative Democracy ( Republic Government, Parliamentary Government ), Constitutional monarchy.
The term error-correction relates to the fact that last-period's deviation from a long-run equilibrium, the error, influences its short-run dynamics. Thus ECMs directly estimate the speed at which a dependent variable returns to equilibrium after a change in other variables.

Rikers Island is a 413-acre (167.14-hectare) [1] [2] prison island in the East River in the Bronx [3] that contains New York City 's largest jail. [4] [5] Named after Abraham Rycken, who took possession of the island in 1664, the island was originally under 100 acres (40 ha) in size, but has since grown to more than 400 acres (160 ha).
The geography of New York (state) varies widely. Most of New York is dominated by farms, forests, rivers, mountains, and lakes. New York's Adirondack Park is larger than any U.S. National Park in the contiguous United States. [2] Niagara Falls, on the Niagara River as it flows from Lake Erie to Lake Ontario, is a popular attraction. The Hudson River begins near Lake Tear of the Clouds and ...
The Bonferroni correction can also be applied as a p-value adjustment: Using that approach, instead of adjusting the alpha level, each p-value is multiplied by the number of tests (with adjusted p-values that exceed 1 then being reduced to 1), and the alpha level is left unchanged. The significance decisions using this approach will be the same ...
