Hi there. I am converting some Matlab code to SAS code. In Matlab, there is a built-in function that calculates the matrix exponential of a matrix called EXPM. There is no such built-in function for PROC IML. Does anyone know how to write the SAS code to produce the same result as EXPM? Thank you!

Got it. Thanks!

What if I have many values? How to expand v{i} = v{i} * v{i-1}; ?

Hi I've write another post to ask the question more clearly. https://communities.sas.com/t5/SAS-Programming/Write-codes-to-show-increment-of-a-sequence/m-p/884599#M349484

Hi all. I would like to transform table 1 to table 2. Table 2 means the bigger value has to times all the previous values. How do I write the code to show such increment? Thanks! Table 1: Value1 Value2 Value3 5 6 7 Table 2: Value1 Value2 Value3 5 5*6 5*6*7

Hi all. I would like to write codes to transform table from Table 1 to Table 2. Thank you! Table 1: ID Value1 Value2 Value3 1 1 2 3 2 4 5 6 3 7 8 9 Table 2: ID Value4 Value5 Value6 1 1-(1-1) 1-(1-1)(1-2) 1-(1-1)(1-2)(1-3) 2 1-(1-4) 1-(1-4)(1-5) 1-(1-4)(1-5)(1-6) 3 1-(1-7) 1-(1-7)(1-8) 1-(1-7)(1-8)(1-9)

It's to incorporate other codes.

Please use data step if possible.

Hi all, I am trying to sum the cost to get the variable TOTAL (it only has ID and cost in the original table). Please see below. Thank you in advance! ID COST TOTAL 1 10 100 2 40 100 3 50 100

Hi All. I am doing a multilevel model using PROC GLIMMIX. proc glimmix data=schools method=quad; class school_id class_id; model score = class_id / solution dist=binary link=logit; random intercept / subject=school_id solution; run; Result: Covariance Parameter Estimates Cov Parm Subject Estimate Standard Error Intercept school_id 0.04852 0.39480 How do I output the p value for this estimate of parameter?

Hi All, I've got a SAS data set like the one below. The second and third rows are the mean and median for the total fee, respectively. Similarly, the last two rows are the mean and median for the unit, respectively. This table is hard to do analysis. I would like to add some indicators to differentiate the two sets of mean and median. Not sure how to do. Thank you in advance. Variable Value total_fee mean 100 median 110 flag_customer 1000 unit mean 10 median 12
