In the particular case when there are only two values – basic (Pb) and current (PT), the pace of growth determine by the formula:Tr = (PT / Pb) * 100%.When determining the annual average tempand growth as the basic indicator, the numerical value characterizing the studied phenomenon, measured at the end of the previous period, i.e. on 1 January of the year for which you are defining the average pace of growth. This value must be expressed in absolute values.
If the pace of growth is calculated as a ratio, the baseline is assumed to be 1 or 100, if you count it in percentage. In the calculation of basic tempos growth for each month of the year, all indicators at the end of each month correlate to the underlying index on 1 January. If you calculate chain indices, the base should take the figure for the previous period. To calculate the average tempand growth the use of chain indices.
The period analyzed is the calendar year from 1 January to 31 December. You must have the information and values in absolute terms at the end of each month, together with the base value, their number should be equal to 13. Calculate chain the pace ofs growth for each month. You should have 12 values the pace ofs growth for each calendar month. This is a very important characteristics. If you calculate them for several years and to analyze the results, you will be able to see and then take into account seasonal fluctuations.
The annual average tempand growth (Sgtr) are already free from the influence of seasonality. To define it, put all the chain figures for the year and divide them by 12:SHTR = (TP1 + TP2 + TP3 +...+Тр11 +Тр12) / 12.
