v6 v7 12 12 }}} 13 13 14 I want to compare 2 plugins A and B. 15 A has 100 resolved tickets out of 200 and has 4.5 average rating from 300reviews.16 B has 20 resolved tickets out of 20 and has 4.9 average rating from 2000reviews.14 **I want to compare 2 plugins A and B:** 15 A has **100** resolved tickets out of **200** and has **4.5** average rating from **300** reviews. 16 B has **20** resolved tickets out of **20** and has **4.9** average rating from **2000** reviews. 17 17 18 So for A and B the multiplier from support threads resolved is:18 So for **A** and **B** the multiplier from support threads resolved are: 19 19 {{{ 20 20 Math.log10(100 + 2) = 2.0 -- A … … 22 22 }}} 23 23 24 2 vs 1.34, it seems to make a real difference.24 It seems to make a real difference. 25 25 26 When you calculate the rating lower bound with new algorithm for plugin A with 4.5 rating ~300 reviews it is 4.33, and same for a plugin with 4.9 rating ~2000 reviews it is 4.87. 26 Now let's calculate the rating lower bound with new algorithm for plugin **A** and **B**: 27 27 28 28 {{{ 29 $wilson->rating_lower_bound(4.5, 300, array(1, 5), array('correction' => true)) = 4.33 30 $wilson->rating_lower_bound(4.9, 2000, array(1, 5), array('correction' => true)) = 4.87 29 $wilson->rating_lower_bound(4.5, 300, array(1, 5), array('correction' => true)) = 4.33 # A 30 $wilson->rating_lower_bound(4.9, 2000, array(1, 5), array('correction' => true)) = 4.87 # B 31 31 }}} 32 32 33 So the multiplier is sqrt(4.33) vs sqrt(4.87)for rating.33 So the multiplier is **sqrt(4.33)** vs **sqrt(4.87)** for rating. 34 34 35 35 {{{
