Absolute growth and other statistics

analysis of how intense and fast changes occur over time, is carried out using statistical performance indicators.Calculate they can be on a variable or a fixed base of comparison.This compared level is called "reporting", and the one which is compared - "basic".For statistical indicators include:

- growth rates;

- growth rates;

- absolute increases;

- the absolute value of one percent.

calculating the indicators on a regular base, there is a comparison of each analyte level with the base.Among the speakers to those selected entry level or the point where we start the analysis of a phenomenon or process.For example, if the analyzed period from 2008 to 2013, then 2009-2013 compared with the 2008 figures, which are calculated at the same time, referred to as "basic".

calculating the figures on the basis of the variable analyzed each level of the previous (eg, in the interval 2008-2013, in 2009 compared with 2008, 2010 - 2009, etc.).Indicated figures are called "chain".

most important indicator

is a time series of absolute growth.He characterizes the change in a positive or negative direction for a certain period of time.The variable base its variation called "growth rate."

Accordingly, the absolute increase can be basic or chain.They are also linked: the set of successive chain performance is the baseline, which is a total increase over the period.

To estimate the intensity for a certain period, it is necessary to determine the rate of growth (decline).It is defined as the ratio between the baseline and reporting.The growth rate is measured as a percentage.To determine the ratio of this index, it is necessary to translate the value of a unit.It shows what proportion compared level is between the base or previous.The rate of growth can not be a negative number.

Baseline growth rate for the entire period of time - is the product chain.There

indicators such as the rate of growth (or contraction), which shows the percentage difference between the levels.If the absolute growth divided by the value of the level adopted for the database, you get this value.It can also be calculated by subtracting 100 from the growth rate or rate of growth unit.It is measured as a percentage, and ratio - expressed as a decimal.The latter can be both positive and negative, and zero.

Behind these figures lies the absolute value of one percent growth - the absolute increase in relation to the growth rate for a specific period of time.This figure is calculated as a percentage.

The above characteristics allow to compare the dynamics of developing and related events over a fairly long period of time, as well as compare the dynamics of the various phenomena of the countries, periods in history, etc.And it should be noted that the evaluation of processes and phenomena in the time necessary to examine all of these indicators together to form a complete picture.
