Introduction Statistical distributions describe how values in a dataset are spread or distributed across possible outcomes. Understanding distributions helps us predict, analyze, and interpret data. Let’s break down some common statistical distributions in simple terms: 1. Normal Distribution Also called a Gaussian distribution or a bell curve, the normal distribution is one of the most…

Introduction Hypothesis testing is a statistical method used to make decisions or draw conclusions about a population based on a sample of data. It’s like having a “mini-experiment” to test whether what we see in the sample also applies to the larger group (the population). Let’s break down the key concepts: 1. What is a…

Introduction A Confidence Interval (CI) is a range of values that we believe, with a certain level of confidence, includes the true value of a parameter (like the average or proportion) in a population. Confidence intervals are commonly used in statistics because they help us understand the accuracy of our estimates. Key Components of Confidence…

Introduction Time Series Analysis is a statistical method used to analyze data points collected or recorded at specific time intervals over a period. It’s widely used in various fields, like finance, weather forecasting, stock market analysis, and more, to identify patterns, trends, and seasonality in data. Two fundamental concepts in time series analysis are stationarity…

Introduction Time Series Analysis is a method for analyzing data that is collected over time. When you observe something over regular intervals (like daily temperature, monthly stock prices, or quarterly sales), you’re looking at a “time series.” It helps in making predictions about future values based on historical patterns. One popular technique in time series…

What is Time Series Analysis? Time series analysis is a technique used to study a sequence of data points collected or recorded over time. These data points are gathered at successive, equally spaced points in time (like daily, monthly, or yearly), capturing how something changes over a period. By analyzing these patterns, we can gain…

Introduction Econometric methods are a set of statistical tools used in economics to analyze data and uncover relationships between different economic variables. One of the most popular and fundamental econometric methods is linear regression. Linear regression helps us understand and predict how one variable (known as the dependent or response variable) changes in response to…

Introduction Econometric methods using Panel Data Analysis involve techniques to analyze datasets that combine both cross-sectional and time-series data. This approach is incredibly useful in economics, social sciences, and finance, where we often want to understand how certain variables behave over time across multiple entities like individuals, firms, or countries. What is Panel Data? Panel…
