The Statistics Indonesia in 2018 has released the official projection of Indonesia's population 2015–2045, [3] which are based on previous census in 2010 and the 2015 Indonesian population survey between censuses (SUPAS).
The original model uses an iterative three-stage modeling approach: Model identification and model selection: making sure that the variables are stationary, identifying seasonality in the dependent series (seasonally differencing it if necessary), and using plots of the autocorrelation (ACF) and partial autocorrelation (PACF) functions of the dependent time series to decide which (if any ...
In statistics, the method of moments is a method of estimation of population parameters.The same principle is used to derive higher moments like skewness and kurtosis. It starts by expressing the population moments (i.e., the expected values of powers of the random variable under consideration) as functions of the parameters of interest.
The core idea behind random projection is given in the Johnson-Lindenstrauss lemma, [2] which states that if points in a vector space are of sufficiently high dimension, then they may be projected into a suitable lower-dimensional space in a way which approximately preserves pairwise distances between the points with high probability.
The Gall–Peters projection of the world map. The Gall–Peters projection is a rectangular, equal-area map projection.Like all equal-area projections, it distorts most shapes.
Arithmetic is the fundamental branch of mathematics that studies numbers and their operations. In particular, it deals with numerical calculations using the arithmetic operations of addition, subtraction, multiplication, and division. [1]
Behrmann projection of the world The Behrmann cylindrical equal-area projection with Tissot's indicatrices of deformation. The Behrmann projection is a cylindrical equal-area map projection described by Walter Behrmann in 1910. [1]
Gall stereographic projection of the world. 15° graticule. Gall stereographic projection with 1,000 km indicatrices of distortion. The Gall stereographic projection, presented by James Gall in 1855, is a cylindrical projection.
