    Log-transforming Only the Dependent Variable

    For the regression: ln(gestation) = 5.28 + 0.0104×Birthweight For the birthweight and gestation data, Minitab tells us that coefficient of birthweight(b1) = 0.01041. minitab output: and therefore: exp(b1)=exp(0.010410)=1.01 The result tells us that the predicted median gestation changes by...

    Estimating main effects in a two factorial log linear model when applied to RNA-seq

    Hi everybody, I'm going to apply multiDE, an R package for detection of DEG in multiple treatment conditions, on some RNA-seq time series data... (I wanna assume each time point as a treatment condition) Let's assume Yidg denotes the normalized read counts for sample "i", in condition "d"...

    Log-Linear

    Hi all, I have a sample data of Mortality vs GDP. I need to make a Log-linear regression analysis. I transformed the data to log scale and then I apply linear regression. So,I take a result as follows : SUMMARY OUTPUT Regression Statistics Multiple R...

    Why regression models use log or exponential value?

    I am not very familiar with statistic. Any statistician can help me to clarify what the difference are between exponential value and log value. I found in academic papers that regression models are usually shown in exponential value or log value. 1) what is the difference between them? 2)...

    analysis for sparse contingency table

    I am analyzing a 2x2x3x2 contingency table. The covariates are treatment (2 different kinds, TR1 and TR2, both binary), location of treatment (3 levels A, B, C), and the outcome is an event that either occurred or did not occur. The table is large compared to the sample size, and observing the...

    Interpretation of linear-log regression model (Neep Help)

    Dear All, I had a problem with my data of growth in percentage regarding negative and positive values due to which I could not transform it into log and get rid of heteroskedasticity issue. However, I found out another way to get rid of negative values i.e. adding a constant with each...

    Estimates from a log-linear regression model

    Hello all, I am estimating a economic growth regressions using dynamic panel data. My specification is as folllows: Ln(Y_i,t) = a*Ln(Y_i,t-1) + b*X_i,t + e_i,t - Y measures income per capita - X is the independent variable of interest, which represents a certain share of GDP (e.g...
