The calculator below makes the calculation of derived indicators of analytical time series.
Rows of dynamics can be called rows, which are arranged in chronological order parameters describing change any values in the time period. Rows of speakers includes 2 basic elements: time indicators - t and the corresponding value of the index - Y.
Rows of speakers is: instantaneous and interval.
Moment time series show the status of the study on the value of a particular time. Interval rows indicate the status of the study values for individual intervals.
Analytic derivatives indices
1. Absolute growth
The difference between the values of two parameters of a number of speakers.
Basic absolute increase - the difference between the current value and the value received for the permanent base of comparison
Chain absolute increase - the difference between the current and previous values
2. Growth rate
The ratio of the two levels of a number (may be expressed as a percentage).
The baseline growth rate - the ratio of the current value and the value received for the permanent base of comparison
Chain growth rate - the ratio of the current and previous values
3. Growth rate
The ratio of the absolute gain to compare metrics.
The baseline growth rate - the ratio of absolute growth and basic values adopted for the constant base of comparison
Chain growth rate - the ratio of absolute growth of chain and the previous value of the indicator
4. Acceleration
The absolute acceleration - the difference between the absolute growth for the period, and the absolute increase in the previous period of equal duration. Measured only chain method
The relative acceleration - the ratio of the chain growth rate for the period and chain growth rate in the previous period
5. The rate of increase
The ratio of the absolute increments chain to the level adopted for the constant base of comparison
6. The absolute value of one percent growth
The ratio of absolute growth to the rate of growth, expressed as a percentage.
After the disclosure of the formula is simplified.
For generalizing the characteristics of the dynamics of the studied series of calculated average dynamics.
Mean dynamics
1. Mid
Characterized by a typical value indicators
The dynamic range of the interval is calculated as the simple arithmetic average of
The dynamic range of the torque with equal time intervals between samples as the chronological average
2. Average absolute increase
Generalizing indicator of the speed of the absolute values of changes in the dynamic series
3. The average growth rate
Generalizing characteristic of the growth rates of a number of speakers
(Root of degree i - 1)
4. The average growth rate
Attitude is also that between the growth rate and growth rate
All derivatives and averages given here are calculated in the calculator (see. Below) as the user enters the number of values in the table.
