Generalized additive models (GAMs) have become an important tool for modeling data flexibly. These models are generalized linear models where the outcome variable depends on unknown smooth functions of some predictor variables, and ...

A couple of years ago, I wrote about the paradoxical difficulty of visualising a difference in means between two groups, while showing both the data and some uncertainty interval. I still feel like many ills in science come from our inability to interpret as simple comparison of means. Anything with ...

Using R and the anova function we can easily compare nested models. Where we are dealing with regression models, then ... Read moreHow to Compare Nested Models in R

Sang-Heon Lee This article explains how to estimate parameters of the linear regression model using the Bayesian inference. Our focus centers on user-friendly intuitive understanding of Bayesian estimation. From some radical point of view, we regard the Bayesian model as the average of multiple models generated with slightly different parameter ...

Sang-Heon Lee This article derives the swaption pricing formula using Black model, which is a lognormal model. We present the detailed calculation example using R code. This work is a prerequisite for the calibratiion of Hull-White or LGM (Linear Gaussian Markov) model. The calibration of parameters of no-aritrage term structure ...

Artists in the R community have been using the #rtistry hashtag to demonstrate their gorgeous, dynamic art using only the R programming language. Their creations are amazing and they inspired me to try out generative art this dreary Sunday. I ...

Association strength, when the hypothesis of independence of attributes in a contingency table is rejected by performing a chi-square test, ensures the association between... The post How to Measure Contingency-Coefficient (Association Strength) appeared first on finnstats.

Sang-Heon Lee This article explains how to calculate DNS shock scenarios based on IAIS (2019). We implement DNS shock generating algorithm using R code with some modification. IAIS DNS Shock Generating Algorithm Risk-based Global Insurance Capital Standard is for the regulatory capital requirements against the unexpected loss of insurance companies. Especially ...

Sang-Heon Lee This article explains how to estimate parameters of the dynamic Nelson-Siegel (DNS) model (Diebold and Li;2006, Diebold, Rudebusch, and Aruoba;2006) using Kalman filter. We estimate not only parameters but also filtered latent factor estimates such as level, slope, and curvature using R code. Dynamic Nelson-Siegel model 1. DNS modelThe ...

Sang-Heon Lee This article explains how to estimate parameters of the Arbitrage-Free dynamic Nelson-Siegel (AFNS) model (Christensen, Diebold, and Rudebusch; 2009, Christensen, Diebold, and Rudebusch; 2011) using Kalman filter. We estimate not only parameters but also filtered latent factor estimates such as level, slope, and curvature using R code. 1. AFNS modelAFNS model ...

One-way ANOVA is a test used to assess whether there is a statistically significant difference between the mean of groups. There is 1 response numeric variable and 1 explanatory categorical variable with more than 1 level. ANOVA considers the probabili...

Obviously, it seems absolutely essential to put a lot of resources into ramping up world-wide vaccine production with the goal to ensure that quickly almost everybody in the world has the chance to become vaccinated. But is a waiver of patents for Covi...
