A time series ratio is a quantitative measure that compares values at different points in time within a time series dataset. It is often used to analyze trends, seasonality, or cyclical patterns by expressing one value as a proportion of another, typically in relation to a base or reference period. This ratio helps in understanding changes over time and can be useful for forecasting future values based on historical trends. Examples include calculating the year-over-year growth rate or the month-over-month change in sales figures.
As you expand the Fibonacci series, each new value in proportion to the previous approaches the Golden Ratio.
The ratio of successive terms in the Fibonacci sequence approaches the Golden ratio as the number of terms increases.
The ratio of (distance) / (time), called "speed".The ratio of (speed) / (time), called "acceleration".The ratio of (force) / (area), called "pressure".The ratio of (force) / (acceleration), called "mass".The ratio of (mass) / (volume), called "density".The ratio of (distance) / (volume), sometimes called "fuel economy".The ratio of ( 1 ) / (time), called "frequency".The ratio of (energy) / (time), called "power".
The ratio of arc time to total time is calculated by dividing the duration of the arc time by the overall duration of the total time. If the arc time is represented as ( A ) and the total time as ( T ), the ratio can be expressed as ( \frac{A}{T} ). This ratio indicates the proportion of time spent in the specified arc compared to the entire duration. To express it as a percentage, you can multiply the ratio by 100.
The "golden ratio" is the limit of the ratio between consecutive terms of the Fibonacci series. That means that when you take two consecutive terms out of your Fibonacci series and divide them, the quotient is near the golden ratio, and the longer the piece of the Fibonacci series is that you use, the nearer the quotient is. The Fibonacci series has the property that it converges quickly, so even if you only look at the quotient of, say, the 9th and 10th terms, you're already going to be darn close. The exact value of the golden ratio is [1 + sqrt(5)]/2
The 'golden ratio' is the limit of the ratio of two consecutive terms of the Fibonacci series, as the series becomes very long. Actually, the series converges very quickly ... after only 10 terms, the ratio of consecutive terms is already within 0.03% of the golden ratio.
As you expand the Fibonacci series, each new value in proportion to the previous approaches the Golden Ratio.
The ratio of the first line of the Lyman series to the first line of the Balmer series in the hydrogen spectrum is 1:5.

The absolute value of the common ratio is less than 1.
The ratio of arc time to total time is calculated by dividing the duration of the arc time by the overall duration of the total time. If the arc time is represented as ( A ) and the total time as ( T ), the ratio can be expressed as ( \frac{A}{T} ). This ratio indicates the proportion of time spent in the specified arc compared to the entire duration. To express it as a percentage, you can multiply the ratio by 100.

The ratio of on time to total time is the percentage of time that an event or activity is done correctly or according to schedule, out of the total time available. This ratio is often used to measure efficiency and reliability in various processes.
