Here's a breakdown of their individual effects:<br /><br /><a href="http://projectcentersinchennai.co.in/Final-Year-Projects-for-CSE/Final-Year-Projects-for-CSE-Machine-learning-Domain" title="Machine Learning Final Year Projects" rel="nofollow">Machine Learning Final Year Projects </a><br /><br /><br />Scaling a Random Variable:<br /><br />Multiplying by a constant (k): When you multiply a random variable X by a constant k, it affects both the mean (average) and standard deviation:<br />Mean: The new mean becomes k * μ (mu), where μ is the original mean of X.<br />If k is positive (e.g., multiplying by 2), the mean is scaled proportionally in the same direction.<br />If k is negative (e.g., multiplying by -2), the mean is scaled in the opposite direction and flips sign.<br />Standard Deviation: The standard deviation (σ) is also scaled by the absolute value of k: new standard deviation = |k| * σ.<br /><br /><a href="http://projectcentersinchennai.co.in/Final-Year-Projects-for-CSE/Final-Year-Projects-for-CSE-Deep-learning-Domain" title="Deep Learning Projects for Final Year" rel="nofollow">Deep Learning Projects for Final Year</a><br /><br />The standard deviation increases proportionally with the absolute value of k.G Ahttps://www.blogger.com/profile/16456068563110018446noreply@blogger.comtag:blogger.com,1999:blog-1042702913368601588.post-25213750250760647542020-07-25T09:07:44.977-07:002020-07-25T09:07:44.977-07:00Pretty good post.
