LOcal regrESSion (LOESS) or LOcally WEighted Scatter-plot Smoother (LOWESS) LOESS or LOWESS is a nonparametric technique to fit a smooth curve through points in a scatter plot. This approach uses locally estimated linear regression at its core. The following code illustrates how to include a loess line using the ggplot2 package. library(ggplot2) set.seed(1) x <- rnorm(60) y <- c(rnorm(40), 10, rnorm(19)) df <- data.frame(x=x, y=y) ## Without weights ggplot(data=df, aes(x=x, y=y)) + geom_point() + geom_smooth(method=loess, legend=FALSE) Furthermore your can plot loess smoothing weighting the observations as follows:
Let’s see how to format your model outputs with parameters package in R by Lüdecke et al. (2020). Fit a simple linear regression model #install.packages("parameters") library(parameters) library(magrittr) library(gt) library(see) model <- lm(Volume ~ Height + Girth, data=trees) Reporting model parameter estimates model %>% model_parameters() Parameter | Coefficient | SE | 95% CI | t(28) | p -------------------------------------------------------------------- (Intercept) | -57.99 | 8.64 | [-75.68, -40.29] | -6.71 | < .

The most common problem while learning Statistics is that students’ lack of understanding of the basic terminologies, notations, definitions and concepts. Think of Statistics as building blocks, and you need a solid foundation to move forward. Here, I explain five common terms in Statistics: i) Parameter, ii) Statistic, iii) Random Variable, iv) Estimator, v) Estimate and their notations. I will start with the definition of Population and Sample. A population is a complete collection of individuals/ objects that we are interested in.
