Autoregressive integrated moving average

In statistics and econometrics, and in particular in time series analysis, an autoregressive integrated moving average (ARIMA) model is a generalization of an autoregressive moving average (ARMA) model. These models are fitted to time series data either to better understand the data or to predict future points in the series (forecasting). They are applied in some cases where data show evidence of non-stationarity, where an initial differencing step (corresponding to the "integrated" part of the model) can be applied to reduce the non-stationarity.

Non-seasonal ARIMA models are generally denoted where parameters p, d, and q are non-negative integers, is the order of the Autoregressive model, is the degree of differencing, and is the order of the Moving-average model. Seasonal ARIMA models are usually denoted , where refers to the number of periods in each season, and the uppercase refer to the autoregressive, differencing, and moving average terms for the seasonal part of the ARIMA model. ARIMA models form an important part of the Box-Jenkins approach to time-series modelling.

Local government in Connecticut

The primary unit of local government in the U.S. state of Connecticut is its 169 towns. Each of these towns may contain incorporated cities or boroughs, as well as unincorporated villages.

New England towns are geographically similar to civil townships in that the entire territory of the state is completely subdivided into towns. However, they differ primarily in that New England towns, particularly in Connecticut, have broad home rule, and have powers comparable to those that a city in other states would normally have. There are advantages and disadvantages to this system: residents have a greater voice in the decision-making process over local issues. On the other hand, the state's delegation of broad powers to the towns sometimes results in bitter rivalries between towns stemming from projects and programs that encompass multiple towns, as town residents and officials have historically placed local interests ahead of the interests of the region or state as a whole. Decades of legal battles between Bridgeport and Stratford over the expansion of Sikorsky Airport and political fighting between Norwalk and Wilton surrounding construction of the US 7 Freeway are examples.

Administrative divisions of Wisconsin

The administrative divisions of Wisconsin include counties, cities, villages and towns. In Wisconsin, all of these are units of general-purpose local government. There are also a number of special purpose districts formed to handle regional concerns, such as school districts.

Whether a municipality is a city, village or town is not strictly dependent on the community's population or area, but on the form of government selected by the residents and approved by the Wisconsin State Legislature. Cities and villages can overlap county boundaries, for example the city of Whitewater is located in Walworth and Jefferson counties.

County

The county is the primary political subdivision of Wisconsin. Every county has a county seat, often a populous or centrally located city or village, where the government offices for the county are located. Within each county are cities, villages and towns. As of 2015, Wisconsin had 72 counties.

A Board of Supervisors is the main legislative entity of the county. Supervisors are elected in nonpartisan elections for two-year terms (except in Milwaukee County where the Milwaukee County Board of Supervisors served four years). In May 2013, the Wisconsin Legislature passed a bill that will reduce the terms of office from four-years to two-years for the Milwaukee County Board of Supervisors. The type of executive official in each county varies: 11 counties have a County Executive elected in a nonpartisan election for a four-year term; 20 counties have appointed County Administrators; and 41 have appointed Administrative Coordinators. Other officials include sheriffs, district attorneys, clerks, treasurers, coroners, surveyors, registers of deeds, and clerks of circuit court; these officers are elected for four-year terms. In most counties, elected coroners have been replaced by appointed medical examiners. State law permits counties to appoint a registered land surveyor in place of electing a surveyor.
