two-way regression modelThis paper considers inference on fixed effects in a linear regression model estimated from network data. An important special case of our setup is the two‐way regression model. This is a workhorse technique in the analysis of matched data sets, such as employer–...

where d1 is 1 when i=1 and 0 otherwise, d2 is 1 when i=2 and 0 otherwise, and so on. d1, d2, ..., are just dummy variables indicating the groups, and v1, v2, ..., are their regression coefficients, which we must estimate. ...
The threshold for battery-free UAVs was calculated by interpolating the irradiance required to meet the experimental top speed according to the most conservative regression of Fig.3. To achieve a velocity of 15 m/s, 200 grams-force of thrust is required. Using the linear regression to estimate,...
The regression results indeed suggested that sleep disturbances may mediate the association between job insecurity and MD. The finding that job insecurity increases the odds of sleep disturbances may be the immediate (or primary) effect of the cognitive or emotional strain attributed to that fear (e...
In particular, prolonged survival was observed in several patients with SCLC treated with the vaccine, and in one patient a complete regression of the tumor was reported [83]. But perhaps for Vaxira the more interesting results came from NSCLC patients. In a first study involving 71 stage IIIb...
The proportion of participants achieving target blood pressure control at 6 months was analyzed using log-binomial regression (binomial distribution with a log link) with the treatment group and use of blood pressure–lowering therapy at baseline as fixed effects and trial center as a random effect...
on the Nelson-Siegel model for both yield curves. The term α is the intercept of the regression line, which represents the expected excess return of the bond when the yield curve change is zero. The term β is the slope of the regression line, which represents the expected excess return ...
GD is extensively used in the field of Machine Learning to optimize parameters such as coefficients in linear regression problems or weights in neural networks. The GD algorithm starts with an initial guess for the function input parameters, and then iteratively adjusts them in the direction that ...
The core model underlying SmartPath is the prediction of DNA yield per slide using linear regression on extracted imaging features. To acquire a training set, the Tempus database was searched for slides scanned between January 2018 and January 2020 containing lung, breast, or colorectal cancer (CR...
