问题 now I have one formula: int a = 53, x = 53, length = 62, result; result = (a + x) % length; but how to calculate reverse modulus to get the smallest "x" if I known result already (53 + x) % 62 = 44 //how to get x i mean what's the formula or logic to get x 回答1: private int ReverseModulus(int div, int a, int remainder) { if(remainder >= div) throw new ArgumentException("Remainder cannot be greater than or equal to divisor"); if(a < remainder) return remainder - a; return div + remainder - a; }

问题 I am not able to resolve the issue that when lm(sformula) is executed, it does not show the string that is assigned to sformula . I have a feeling it is generic way R handles argument of a function and not specific to linear regression. Below is the illustration of the issue through examples. Example 1, has the undesired output lm(formula = sformula) . The example 2 is the output I would like i.e., lm(formula = "y~x") . x <- 1:10 y <- x * runif(10) sformula <- "y~x" ## Example: 1 lm(sformula)

问题 This question already has answers here : Formula with dynamic number of variables (5 answers) Closed 3 years ago . I am trying to build a regression model with lm(...). My dataset has lots of features(>50). I do not want to write my code as lm(output~feature1+feature2+feature3+...+feature70) . I was wondering what is the short hand notation to write this code. 回答1: You can use . as described in the help page for formula . The . stands for "all columns not otherwise in the formula". lm(output

问题 Prior Rlet Rcall Resolved So I want Excel to find and replace all words starting with "R" in a certain column and change them all to "Resolved". It seems like a simple substitute or replace, but I can't seem to get it to work with only words starting with "R". Thanks! 回答1: You are asking for a "formula". That is usually something you enter into a cell. If that is the case, then if you have the list of words in the A column, you could put the following formula in cell B1: =IF(LEFT(A1, 1)="R",
