The survey uses factor analysis to find important factors using a questionnaire consist of 29 variables, which were reduced to 22 questions after considering skewness statistics. Cronbach alpha is calculated as 0.86, which validates the questionnaire. The survey detects six factors influencing feasibility...
it is convenient to discretise time according to clock ticks and track time in terms of the number of clock ticks. Alternatively, time can be measured in units of absolute time, considering that, on average, there aren
Moreover, the observed image quality is significantly influenced by the quality of the prepared smear in terms of uniformity of erythrocyte distribution (smearing), staining, and cleanliness. The analysis of an extensive data collection obtained during general laboratory operations also showed that conven...
(Dunbar, 2000; Dunbar, 2003; Hill and Dunbar, 2003; Gonçalves et al., 2011; Arnaboldi et al., 2013a) and the skewness of social relationships (Zhou et al., 2005; Hossmann et al., 2011; Arnaboldi et al., 2012; Hu et al., 2012; Song et al., 2012; Arnaboldi et al., 2013...
A total of 1334 patients were included in the analysis. The percentages of missing data for each variable were below 5%. Missing values were imputed, as described previously in [2]. In all, 107 patients (8.0%) had tumors that were detected with ultrasound alone but not with mammography. Cl...
To correct for skewness in the frequency distri- bution, for each critical item, raw frequencies were transformed into log frequencies , using the following formula: log (.5 1 raw frequency). For example, the log frequency of sleep is 1.82 [i.e., log (65.5)], whereas the log frequency...
journals. The WoS database was searched with species scientific name used in the field “Topic”, and Crop Science in the “Publication Name” field. The results of CSw searches were visually inspected and the papers describing registration of a new germplasm or cultivar were deleted from the ...
of data points in the multidimensional data set dominated by the first data point in every dimension, determining a first skewness value for the first data point, the first skewness value corresponding to a size of a first dimension of the first data point relative to a combined size of all...
Sugar content (in μg) was 10 + log-transformed before analysis to correct for left-skewness in residuals and to meet the model assumptions of normality and hetero- scedasticity. We included in the model other potentially relevant variables know to impact nectar's sugar con- tent:...
It is a requisite to check the distribution of estimated parameters before proceeding with statistical analysis. In pharmacological calculations, many parameters need to be converted to logarithm to remove skewness. To analyse the distribution of parameter τ, 1000 sets of concentration-response curves ...
