Can Bayesian statistics really determine in advance if the bid you are offering will be the winner or just another loser? And, if the metrics forecast a loss, can the same algorithm tell you what to change in order to win instead?
Competitive bidding is where big money sales opportunities are won or lost, and there are four (4) rules that can help you turn a losing situation into a winning sale.
These four rules help you better understand what the customer wants, examine what competitors might do in response and how to beat them, while helping you to offer the best bid, optimized for yours and your prospective customer’s intended outcome. Statistical metrics evaluate your probability of success against the competition and help you more objectively determine how to win. But how can you get at the foundational issues that will determine who will win?
Learning objectives:
Learn the Four Rules that help you understand what will actually determine the customer’s decision.
Visualize your bid head-to-head against the competition and employ objective metrics to determine if you will win.
Identify weaknesses in your offer that must be improved for your bid to beat the competition.

8. Why are the patents and new approaches
needed?
Because usual methods typically have hidden bias, hidden risks
and hidden errors.
► MAJOR CONUNDRUM: We believe in the usual approaches
and keep using them because the errors are hidden so are
missed and not considered.
► E.g., Behavioral research. If we believe the decision will be 70-80%

DCF and Other Financial Formula Can

Gordon growth model:
$10 million payout in one year, g = growth rate, r= rate of return
Value, DCF = $10/ (r – g) (in millions)
Example 1: r = 12% , g = 10%
Value = $10/ ( 0.12 - 0.10) = $10/(0.02) = $500 million
Example 2: r = 12% , g = 11% growth rate increased by 10%
Value = $10/ ( 0.12 - 0.11) = $10/(0.01) = $1 billion

More Accurate Using Better Math
Two quantities, 40 and 10
What percentage is 40 of total?
40/( 40 + 10) = 40/50 80%
Suppose 25% error in 40. Could be 30 – 50.
What is percentage of the total now?
30/(30 +10) 75%
50/(50 + 10) 83.66%
Much reduced error relative to 80% base --– error less than 7%
ERROR REDUCED FROM 25% TO LESS THAN 7%.
THE MATH IN MOST ALGORITHMS IN COMMON USE CANNOT BE
TRUSTED.
Must use better approaches that reduce error and attack the hidden secret.

Algorithms Increase Risk and Errors, and We Do Not
Know It
Bayesian Algorithm I Use Reduces Risk and Errors
1. “The model was previously shown to be surprisingly robust to obvious violations of
this independence assumption, yielding accurate classification models
even when there are clear conditional dependencies.”
“Many researchers have noted the good performance of SBC, including Clark
and Niblett, Knononenko, Langley and Sage, and Domingos and Pazzani.”
2. Beyond Independence: ..is commonly thought to assume that attributes are independent
given the class, but this is apparently contradicted by the surprisingly good
performance it exhibits in many domains that contain clear attribute
dependences. No explanation for this has been proposed so far. In this paper we show that the
SBC does not in fact assume attribute independence, and can be optimal even
when this assumption is violated by a wide margin
