• Confidence sets show possible values of estimated parameters.
• For one coefficient, it is an interval (line).
• For two coefficients, it becomes a 2D region.
• That region is typically elliptical in shape.

Getting odd on die = 0.33

Getting head on coin = 0.50

0.50 > 0.33, so getting a head is more likely.

Explanation

• A Geometric Sequence is a sequence where each term is obtained by multiplying the previous term by a constant.
• This constant is called the common ratio (r).
• The value of r ≠ 0.
• Sequence grows or decreases depending on r.
