R/d2 and S/C4 estimate the population standard deviation, and compare the differences in CPK and specification limit probabilities
R/d2 and S/C4 are unbiased estimators for estimating the population standard deviation, often used in control charts. The main purpose of these estimation methods is to estimate the population standard deviation from sample data in order to monitor the stability and variability of the process without collecting data for the entire population. Specifically: R/d2 in […]

Urban congestion caused by high population density in large cities: planning the best time to go home
With the arrival of summer vacation, college students can’t wait to pack their bags and prepare to go home to reunite with their families. However, for college students who study in Shanghai, returning home also means facing severe urban congestion problems. First of all, college students go home concentrated in the first few days of […]
Population Optimization Algorithm for Futures Quantification Software: Bacterial Foraging Optimization (BFO)
The Bacterial Foraging Optimization (BFO) algorithm is a fascinating optimization technique for finding approximate solutions to maximization/minimization problems in extremely complex or impossible numerical functions. This algorithm is widely regarded as a global optimization algorithm for distributed optimization and control. BFO was inspired by the social foraging behavior of Escherichia coli. BFO has attracted the […]
ARIMA predicts future population change
ARIMA (Autoregressive Moving Average Model) is a commonly used time series forecasting model that can be used to predict future population changes. The following are the general steps to use the ARIMA model to predict the future population: 1. Data preparation: collect relevant population data, and perform necessary data cleaning and processing to ensure the […]
