Monte Carlo Simulations in R

Monte Carlo Simulations What is Monte Carlo Simulations? One of the main motivations to switch from spreadsheet-type tools (such as Microsoft Excel) to a program like R is for simulation modeling. R allows us to repeat the same (potentially complex and detailed) calculations with different random values over and over again. Within the same software, […]

Different Hypothesis Testing Using R

What is Hypothesis Testing It is a type of inferential statistics that involves extrapolating results from a sample (random) to the entire population. It is used to make decisions based on statistical tests and models that use the p-value, also known as the Type I error or alpha error. Type I Error : When we […]

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 […]
