RSquare provides a measure of the strength of the linear relationship between the response and the predictor. In simple linear regression, RSquare is the square of the correlation coefficient, r. This statistic, which falls between 0 and 1, measures the proportion of the total variation ...
This book is not intended to replace a statistics textbook or be a complete regression analysis guide. Instead, it is intended to be a quick and easy-to-follow summary of the regression analysis output. ‘Interpreting Regression Output Without all the Statistics Theory’ focuses only on basic in...

I'm new to R and logistic regression and have to admit that I don't really know how to interpret the result. I'm trying to compute a pretty simple model with 2 predictors (A and B). When I first try to compute models with the predictors one by one they are both significant. When...

In this case we have one continuous variable (like height) and two categorical ones, again we’ll simulate some data and explore the model output: dat <- data.frame(F1=gl(n = 2,k = 50),F2=factor(rep(1:2,times=50)),X1=runif(100,-2,2)) modmat <- model.matrix(~F1*F2*X1,da...
Finally, we used the logLR output from ash as a measure of support for enrichment (this is the Bayes factor on the log-scale), and we computed the mean l.e. LFC as the average of the posterior mean estimates of the l.e. LFCs taken over all peaks j connected to the gene and with...
Parts-based representations, such as non-negative matrix factorization and topic modeling, have been used to identify structure from single-cell sequencing data sets, in particular structure that is not as well captured by clustering or other dimensional
My question is in interpreting my interaction effect. The car package anova gives me this output: LR Chisq Df Pr(>Chisq) sample_numerosity 4.884 3 0.1804952 sample_length 23.544 4 9.859e-05 *** dot_sizes_mean_c 22.998 1 1.622e-06 *** ...
I am not getting that from my outputs. Many thanks! Hi Ly, Yes, that’s it exactly, as long as there are no other covariates in the model ( you don’t mention that). Reply
