Testing is a crucial activity of product-line engineering. Due to shared commonality, testing each variant individually results in redundant testing processes. By adopting regression testing strategies, variants
In terms of explaining this, we first need to take into account the potential impact of the regression to the mean effect (Mee and Chua, 1991; Kahneman, 2011)2. When best participants are selected during a first measurement, they will tend, by chance alone, to be ...
Linear regression was performed to assess whether age (18–49, 50–64, 65+), gender, or sample group (general population vs. patient) predicted the cumulative difference in individual-level utility decrement values between test and retest. Two separate regressions were estimated, one with the mai...
# Run tests that are tagged as both `regression` and `fast` julia> runtests("test/Database/"; tags=[:regression, :fast]) Filtering by name and tags can be combined to run only test-items that match both the name and tags. # Run tests named `issue*` which also have tag `regressio...
Using linear regression of the semi-logarithmic I/O function, the DPOAE threshold was defined as the value of L2 at which the extrapolated DPOAE amplitude equals 0 µPa, called the estimated distortion-product threshold (EDPT). Significant correlations were observed between EDPTs and audiometric...
observations that contribute to the correlation between learning rates and shifting strategies, we tested this over the two sessions in a mixed-model beta-regression analysis with measures of sessions 1 and 2 nested in participants as random effects using the glmmADMB package (Skaug et al.,2018)....
Missing data were imputed via regression from the other administered measures also used as covariates. A primary question was whether any of R1-4, would differentially affect reliability estimates. As such, after computing reliability estimates at each voxel, we rank ordered them across all ...
We examined the effects of attribute (taste, health), context (natural-cued and health-cued condition), and session (1:5) on healthy choice behavior using a Bayesian hierarchical logistic regression. This regression estimated the probability of selecting the healthier of the two food options as ...
DSM = Diagnostic and Statistical. Manual of Mental Disorders. Solid line = regression (R2 linear = 0.411). Horizontal line = recommended GDS cut-off ≥ 5 for any depression. Vertical dotted line = suggested MADRS cut-off ≥ 13 points for any depression, ...
we calculated the magnitude of TS with 2 commonly used alternative approaches: one that subtracts the pain rating of the first heat pulse from that of the last one14, 33 (in our case, 10th); and another using linear regression to calculate the slope of pain ratings in response to the fi...
