To wrap our heads around this, we will talk in terms of potential outcomes. They are potential because they didn\u2019t happen. Instead, they denote what would have happened in the case some treatment was taken. We sometimes call the potential outcome that happened, factual, and the one that didn\u2019t happen, counterfactual.<\/p><p>As for the notation, we use an additional subscript:<\/p><p>Y_i0 is the potential outcome for unit(i) without the treatment.<\/p><p>Y_i1 is the potential outcome for the same unit(i) with the treatment.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-4829ba8 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"4829ba8\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-80dbba7\" data-id=\"80dbba7\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-ce60f53 elementor-widget elementor-widget-image\" data-id=\"ce60f53\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"371\" height=\"350\" data-src=\"https:\/\/whiteriversmediasolutions.com\/Sony\/uvaftoap\/2023\/03\/abhinav-blog-pic.png\" class=\"attachment-full size-full wp-image-7593 lazyload\" alt=\"\" data-srcset=\"https:\/\/whiteriversmediasolutions.com\/Sony\/uvaftoap\/2023\/03\/abhinav-blog-pic.png 371w, https:\/\/whiteriversmediasolutions.com\/Sony\/uvaftoap\/2023\/03\/abhinav-blog-pic-300x283.png 300w\" data-sizes=\"(max-width: 371px) 100vw, 371px\" style=\"--smush-placeholder-width: 371px; --smush-placeholder-aspect-ratio: 371\/350;width:100%;height:94.34%;max-width:371px\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-fa5b76a elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"fa5b76a\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-ed8ee78\" data-id=\"ed8ee78\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-4c359ab elementor-widget elementor-widget-text-editor\" data-id=\"4c359ab\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h4>Causal Inference in Machine Learning and Business Analytics<\/h4>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-30ab312 elementor-widget elementor-widget-text-editor\" data-id=\"30ab312\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><strong>Average treatment effect<\/strong><\/p><p>Randomized control trials are gold standard for collecting data for machine learning implementations based on causal inference.
