8. Nonconstant growth stock As companies evolve, certain factors can drive sudden growth. This may lead to a period of nonconstant, or variable, growth. This would cause the expected growth rate to increase or decrease, thereby affecting the valuation model. For companies in such situations, you would refer to the variable, or nonconstant, growth model for the valuation of the...

Logistic Regression
In class, we discussed the logistic regression model for binary classification problem. Here, we consider an alternative model. We have a training set {<n, yn) }n where E RD+1 and yn e {0,1}. Like in logistic regression, we will construct a probabilistic model for the probability that yn belongs to class 0 or 1, given en and the...
