## Polynomial Regression Model in R

Polynomial Regression Curve fitting or curve-linear regression are additional words for the same thing. It is used when a scatterplot shows a non-linear relationship. It’s most typically employed with time series data, but it can be applied to a variety of other situations. Let’s use the Nepal Covid data and fit a polynomial models on […]

## Social Network Analysis in R

Social Network Analysis Definition Social networks are simply networks of social interactions and personal relationships. Think about our group of friends and how we got to know them. Maybe we met them while ago from our schooling, or maybe we met them through a hobby or through our community. In fact, 72% of all Internet […]

## R Exercise: Working with Outliers and Fitting Different Machine Learning Models

Extract the Nepal COVID-19 data from Wikipedia to fit the following models with daily deaths as dependent variable and time as independent variable First plot the daily deaths by time and distribute the three outliers (added deaths around timeline of 400) before fitting the following models in the outlier adjusted data on training and testing […]

## R Exercise: Working with Data from JSON API and Performing EDA

Import any data from JSON API This was prepared on Google Colab. Please refer to this link for running R in Google Colab. We are using data from https://data.askbhunte.com/api/v1/covid. We are going to use below packages. jsonlite : It implements a bidirectional mapping between JSON data and the most important R data types. RCurl : […]
