please help me understand an interpretation where in i have log transformed the outcome variable and the coefficient came as negative. The independent variable is a categorical variable. Now while interpreting the result should i take the exponential of the negative coefficient or just the absolute v...
In the regression of log transformed data, logy=αlogx+β+εz (equivalent to equation y=Axα·ω), it is the intercept β=logyx=logA that estimates the percent recovery in logarithm when slope α=1, which means that R doesn't vary over x. Error term ω is multiplicative to x, ...

In terms of cellular fraction estimation, both MuSiC and CIBERSORTx outperformed the standard linear regression methods, though they are also linear regression approaches. Here, we introduce BLADE (Bayesian Log-normAl DEconvolution), a Bayesian method that jointly performs deconvolution and purification ...
normality, or symmetry, can be estimated by finding a transformation such that the third-moment skewness coefficient of the transformed data is zero. In regression, a transformation to constant variance can be defined as the transformation that induces a zero correlation between the squared residuals...

Then the univariate half thresholding operator for a \(L_{1/2}\) penalized linear regression coefficient is given as follows: $$\beta_{j} = Half(w_{j} ,\lambda ) = \left\{ {\begin{array}{*{20}l} {\frac{2}{3}w_{j} \left( {1 + \cos \frac{{2(\pi - \phi_{\lambda ...
Plotting LogD = f(t) leads to the determination of the thermal bleaching rate (kΔ) which may be obtained graphically or by linear regression using a computer. The half lifes may be expressed directly from rate constants by the relation: (3)71/2 = 0.69/kΔ The absorption maximum wa...
