ordinals

问题 I am trying to completely understand difference between categorical and ordinal data when doing regression analysis. For now, what is clear: Categorical feature and data example: Color: red, white, black Why categorical: red < white < black is logically incorrect Ordinal feature and data example: Condition: old, renovated, new Why ordinal: old < renovated < new is logically correct Categorical-to-numeric and ordinal-to-numeric encoding methods: One-Hot encoding for categorical data Arbitrary

问题 I'm trying to explain changes in tree vitality from 1 to 3 (1=green, 2=damage, 3=dry) using climatic variables in an MCMCglmm model. Unfortunately, I am struggling with two questions: 1. How do I interpret the summary of the MCMCglmm model? I see which variables are significant, but what does it mean? Does this mean that with increasing precipitation the vitality gets to 1 (green)? I plotted the posterior means of the model and looks like precipitation and diameter have no influence on the

问题 is it possible in mysql to select a value from a table by specifying the column number instead of the column name ? 回答1: No, you can not use the ordinal value of a column in the SELECT clause. Column order is irrelevant to a database; the ordinal value is based on the list of columns in the SELECT clause. The ordinal value is supported after the SELECT clause - IE: in the GROUP BY , and ORDER BY . That said, using ordinals is not a recommended approach because ordinals are brittle -- if

问题 This question already has answers here : Is there an easy way to create ordinals in C#? (20 answers) Closed 5 years ago . I am wondering if there is a method or format string I'm missing in .NET to convert the following: 1 to 1st 2 to 2nd 3 to 3rd 4 to 4th 11 to 11th 101 to 101st 111 to 111th This link has a bad example of the basic principle involved in writing your own function, but I am more curious if there is an inbuilt capacity I'm missing. Solution Scott Hanselman's answer is the

问题 Is there any elegant way how to get ordinals in word format in js/coffee? Something like this: ordinalInWord(1) # => "first" ordinalInWord(2) # => "second" ordinalInWord(5) # => "fifth" 回答1: I'm afraid the ordinals aren't regular enough to avoid typing each of them out. function ordinalInWord( cardinal ) { var ordinals = [ 'zeroth', 'first', 'second', 'third' /* and so on */ ]; return ordinals[ cardinal ]; } If you need the function work past 20, you can take advantage of the pattern that

问题 Basically I'm looking for something like SELECT ordinal(my_number) FROM my_table which would return 1st 11th 1071st ... etc but preferrably without the use of a stored procedure 回答1: I don't know of a built-in function but it's pretty easy to write: SELECT CONCAT(my_number, CASE WHEN my_number%100 BETWEEN 11 AND 13 THEN "th" WHEN my_number%10 = 1 THEN "st" WHEN my_number%10 = 2 THEN "nd" WHEN my_number%10 = 3 THEN "rd" ELSE "th" END) FROM my_table; 回答2: mysql doesn't have support for this.

问题 for ($rank=0; $rank<100; $rank++) { printf("Your rank: %d%s", $rank, $suffix); } Does there exist a gettext function to localize $suffix to the current language and return, for example: Your rank: 0th Your rank: 1st Your rank: 2nd Your rank: 3rd Your rank: 4th if the current locale is English, and whatever the correct "ordinal" forms of numbers are in other languages when the locale is set to something else? Thank you. 回答1: Not that I know of, but you can use NumberFormatter $nf = new
