I ran biserial correlations between continuous and binary variables in SPSS on a large dataset of 762 patients. I correlated 138 regional brain volumes with 7 binary cognitive outcomes to explore the association between regional brain tissue volumes and cognitive impairment. I got pretty low values ...
First, only the mean values of the continuous scalar interface variables and observable components are relevant for the function of the network and thus for its modularization. The actual distribution of the network states conditioned on these mean values is arbitrary as long as it is consistent wi...
According to this indicator, we can analyze the similarity between manual and automatic results . Furthermore, each Pearson interpretation that has been presented until now may be applied to continuous evaluations parameters, for instance: r(a, t, tt) where a = cvt. On the other hand, some ...
Because the autocorrelation function of a second-order cyclostationary signal is transient in time-lag τ and periodic in time t, the corresponding spectral correlation is continuous in f but discrete in α, thus returning a very distinctive signature as illustrated in Fig. A2 for the signal of ...
Continuous data are expressed as means and standard deviations or medians with 25th and 75th percentiles (or interquartile range, IQR) depending on the normality of the distribution. Binary and categorical data are expressed as counts and percentages. For OS analysis, a Kaplan–Meier analysis was...
Spearman's rank correla- tion coefficient was used to analyze the association between a continuous and binary variable, and the phi coefficient was used to analyze the association between two binary var- iables. Logistic regression models were used to quantify the associations between serological ...
Spouses may affect each other’s sleeping behaviour. In 47,420 spouse-pairs from the UK Biobank, we found a weak positive phenotypic correlation between spouses for self-reported sleep duration (r = 0.11; 95% CI = 0.10, 0.12) and a weak inver
It quantifies the association between two variables: a continuous variable (must be ratio scale or interval scale) and a naturally binary variable. Polychoric Correlation is a measure of agreement between multiple raters for ordinal variables. Interpretation is the same as Pearson’s r. Spearman ...
IS NOT POSITIVE DEFINITE..." and TECH4 shows a correlation greater than 1 between iu and iy. As per my understanding, the syntax splits the one variable into a set of dichotomous yes/no variables and then a continuous variable for those in the yes category. Wouldn't the iu and iy lat...
