The time series year average (clim), the standard deviation (SD), the coefficient of variations (cv), the correlation (corr)., the root mean square errors (rmse) and the bias value of precipitation were used to evaluate the best performed model over Ethiopia.
The data consists of time series from year 5 to year 125 measured every 10 years of the forest stand yield (in (m(^3) /ha) of a certain species or species combination after reforestation.
In the present study, two long time series (∼20 years) of flood claims from property owners have been collected and analysed in detail to investigate the mechanisms and characteristics leading to urban flooding.
An artificial neural network (ANN) is then trained on the available WWTP input-output data, and is subsequently used to simulate the remainder of the influent time series (20 years of dynamic data) generated with the influent disturbance generator.
Secular variation studies developed by Demetrescu and Dobrica (2005, 2014) and Dobrica et al. (2013) on long time series (100 150 years) of observatory data showed that the surface field and its SV are constituted of oscillations at time scales of ~ 11, ~ 22 and ~ 80 years, which are superimposed on a (quasi linear trend denoted steady variation.
To measure the effects of the subsidy on health centre use, we studied changes in the average number of deliveries in each maternity unit by means of relatively long time series (six years).
From this, we make time series by year, and word shift graphs of decades versus the baseline.
Were it possible to further refine Argentina's measured capital input time series every year for capacity utilization levels—something no statistician has yet done we would probably discover similar gaps even in the recession periods.
In method A, we derive the annual estimate of risk from the time series of L years, including the current year of interest as well as L – 1 previous years.
One middle leg per museum specimen was sampled from years in which a reasonable number of specimens were collected, which gave a time series with 4-12 years between samples, covering 77 years (Table 1).
