Analysis paralysis‚ endless meetings‚ and corporate structure have made it painstakingly difficult to come to any real conclusions.

The linear probability model‚ ctd. When Y is binary‚ the linear regression model Yi = β0 + β1Xi + ui is called the linear probability model. • The predicted value is a probability: • E(Y|X=x) = Pr(Y=1|X=x) = prob. that Y = 1 given x • Yˆ = the predicted probability that Yi = 1‚ given X • β1 = change in probability that Y = 1 for a given ∆x: Pr(Y = 1 | X = x + ∆x ) − Pr(Y = 1 | X = x ) β1 = ∆x 5 Example: linear probability model‚ HMDA data Mortgage denial v. ratio of debt payments to income (P/I

marks) Sandra Enright of Techtronics Inc.‚ an electronics supply firm‚ has been examining the times required for stock pickers to fill orders requested from inventory. She has determined that individual order-filling times approximately follow a normal distribution with a mean value of 3.2 minutes and standard deviation of 68 seconds. a) What is the probability that a randomly selected order will require more than three minutes? b) What is the probability that a randomly selected order will

Student ’s t-distribution (or simply the t-distribution) is a continuous probability distribution that arises when estimating the mean of a normally distributed population in situations where the sample size is small” (Narasimhan ‚ 1996). Similar to the normal distribution‚ the t-distribution is symmetric and bell-shaped‚ but has heavier tails‚ meaning that it is more likely to produce values far from its mean. This makes the t-distribution useful for understanding statistical behaviors of random quantities

Learning Log - Activity 3.7 The purpose of the study for learning log –Activity 3.7 was conducting a literature search for suitable papers on stakeholder theory. During the study I used common rules for searching literature: * scoping (and context) (Collins and Hussey‚ 2008); for scoping I usually looking for a last ten-five years literature * key word(s) searching in present I used words such as ‘Globalization”‚ “Sustainability‚ etc. * refining the search on stakeholder theory
