The formula to calculate the Aitchison distance between two generic vectors x and y of length m is: dA x, y = 1 m−1 m ln xi − ln yi 2 m i=1 j=i+1 xj yj (9) As for SMAPE, we computed Aitchison distance on CPM transformed data. For each dataset and for each pipeline,...
either provided by the manufacturer or determined following optimization. The activity meter (dose calibrator) guarantees accurate measurement of the administered activity to the patient, while the gamma camera enables the assessment of the radiopharmaceutical...
It would be advisable to calculate p-values both analytically and by comparison with random sequences that would have to be generated by shuffling the actual viral genomes (preferably, trying Markov models of different orders). Under this approach, it is necessary to generate many (at least, 10...
Since the economic reforms and “opening up” of the Chinese economy, people’s quality of life has greatly improved in China, and rapid social and economic development has occurred. However, in the past, China’s economic development relied more on labour and resource consumption to achieve tra...
1a is \(\gamma = \frac{7}{{16}}\). Therefore, we use Eq. 1 to calculate that the fraction of variants with the orange mutation that survive is \(F_{r,a} = \frac{7}{{16}} \times \frac{{4/7}}{{4/16}} = 1\). Performing the analogous calculation for Fig. 1d correctly...
Building on my last post, now we will map a users location and see how far they have travelled between them. I'll also provide the completed project as...
calculate the economic importance and the supply risk, with an explanation of the different parameters that are considered in these equations. All the parameters in the criticality equations focus on the current situation, which in turn reflects the recent past (average of the latest 5 years, ...
For example, higher gamma diversity can be reached in even-aged shelterwood beech forest landscapes with different development ages, as opposed to uneven-aged continuous cover forests (“Plenterwald”), as a result of heterogeneous microclimate conditions in the understory at the landscape level [...
The ‘gamma-identity’ fit on original data was found to produce the best fit in the NT, LRBC, and AC phases, and was thus used. Differences in runoff between NT, LRBC, and AC were assessed via the Mann–Whitney U test using calculated treatment effects (Te). To calculate Te, the ...
So this is where I wanted to use a multiple regression output And I want to calculate error as well , which error metric would you suggest be best? I wanted to use MAPE but it has the form like diff/actual… where actual is of the form ([lat, long)] so I cant divide it with ...
