问题 I would like to have a little clarification on the definiton of a bucket in SAS hashtable. The question is exactly about the hashexp parameter. According to the SAS DOCs, hashexp is: The hash object's internal table size, where the size of the hash table is 2n. The value of HASHEXP is used as a power-of-two exponent to create the hash table size. For example, a value of 4 for HASHEXP equates to a hash table size of 24, or 16. The maximum value for HASHEXP is 20. The hash table size is not

问题 Hi I am trying to write a macro function with do loop and if statement. I think I have messed up the if-then do and do loop and I can't figure out the problem. I have a table of kids information, which contains columns like age, gender, sports, instruments etc,. My original code, which works, looks like this: data old; set new; if sports in ("football","basketball") and age <=7 then type =1; else if sports='swimming' then type=2; if special_kid=. then do; if piano ^=. and piano_1 ^=. then do;

问题 I created the following macro. Proc power returns table pw_cout containing column Power . The data _null_ step assigns the value in column Power of pw_out to macro variable tpw . I want the macro to return the value of tpw , so that in the main program, I can call it in DATA step like: data test; set tmp; pw_tmp=ttest_power(meanA=a, stdA=s1, nA=n1, meanB=a2, stdB=s2, nB=n2); run; Here is the code of the macro: %macro ttest_power(meanA=, stdA=, nA=, meanB=, stdB=, nB=); proc power;

问题 I export data from R to sas format with package haven . However, when I open my .sas7bdat data. It fails. library(haven) write_sas(M, "C:/Users/user/desktop/MERGED_data.sas7bdat") I provide my data structure below: Here is the properties. I double click the data to open in sas, but it fails and provides the information. Any suggestion? 来源： https://stackoverflow.com/questions/52031042/r-export-to-sas-but-cannot-open

问题 I have dates in excel in the following format 02/15/2011. When I import to excel, the dates are numeric such as 40561. When I convert these in SAS using the code below, I get dates such as 04/01/1946. So far my code is: data Reformat11; set Old; Amount1 = input(Amount, comma10.); DateReceived2 = Input(PUT(DateReceived, 5.), MMDDYY10.); Format DateReceived2 MMDDYY10.; format DateApproved MMDDYY10.; run; Any other Suggestions? 回答1: SAS knows how to import dates from Excel. What it cannot do is

问题 I need to export some results from SAS to Excel. So far, I was using a simple proc export for that but since the export got more complex (multiple proc result s and data sets need to be mapped to one sheet) I need to find an alternative. It seems, ods excel is the way to go - and I agree, it is highly customizable - but I am facing a problem where I am not sure whether it is SAS or Excel related. Problem: When I have a SAS data set with character columns, where the data are strings of digits
