Binary Logistic Regression using SigmaXL Software
Dear friends, we are happy to release our 99th technical video on Binary Logistic Regression (BNR)! BNR is an important statistical technique which helps in determining the effect of variable factors on a discrete binary response! Some application examples can be:
• Effect of pouring temperature, pouring time, carbon equivalent on casting defects such as porosity
• Effect of salary, and experience on attrition
• Bankruptcy prediction based on financial ratios.
Hemnat Urdhwareshe, Fellow ASQ, have explained the mathematical basis of the technique and illustrated the technique with an application example on SigmaXL software. We hope you find the video interesting and useful!
[Read more…]Measurement Systems Analysis using SigmaXL software
Dear friends, many of the viewers had requested for an introductory video on measurement systems analysis (MSA) and Gauge Repeatability and Reproducibility (R&R) Study. We are happy to release this video on MSA! In this video, Hemant Urdhwareshe, Fellow of American Society for Quality, and ASQ Certified Six Sigma Master Black Belt, explains the terminology of measurement systems and also illustrates how to conduct, analyse and interpret the results of a Gauge R&R Study. Hemant has illustrated this with an application example using template from SigmaXL software. Your feedback on the video is welcome!

[Read more…]Sigma Level and PPM Calculation on Excel
Dear friends, I am glad to release our technical video on the subject of ‘Sigma Level vs Defective Proportion and PPM’! In this video, I have tried to explain the definition of sigma level in the context of the relation between tolerance and standard deviation sigma. Sigma Level assessment is an essential step in Six Sigma projects. In this video, I have explained the logic of 1.5sigma shift as was developed in Motorola. The sigma level vs ppm calculations are explained and illustrated using an Excel screen recording. Hope you find this video interesting!
