3. Yearly baseball batting averages: A good example of simple regression is the exercise of predicting a numerical measure of a professional athlete's performance in a given year by a linear function of his or her performance on the same measure in the previous year. Baseball batting averages...
The regression equation’s predicted value for the first of the five records is shown in cell L2 ofFigure 6.3. It is calculated with this equation: =$H$2+$G$2*C2+$F$2*D2 which is then copied and pasted into L3:L6 ofFigure 6.3. You can get the same effect using Excel’sTRENDfun...
We begin with the case of one independent variable, i.e. a logistic regression model of form y =β1x+β0. In particular, we assume this variable is normally distributed. We can estimate the minimum sample size when comparing the null hypothesis H0:β1= 0 with the alterna...

while the fc-head excels in classification tasks. While the fc-head has greater spatial sensitivity than conv-head, which aids in distinguishing between complete and partial objects, it may not be as robust as the conv-head when it comes to the effective regression of the whole object. Overa...

2. Nice properties in ANOVA such as the Grand Mean being the intercept in an effect-coded regression model don’t hold when data are unbalanced. Instead of the grand mean, you need to use a weighted mean. That’s not a big deal if you’re aware of it. But there are a few real ...
