Hello I have a sas program that run automatically every day. In case that have warning or error messages then I want to save the Log file and attach it to email and send it to me. What is the way to do it? Note that I want to send the email +attach log file only in case of error or warning

Dear SAS Community, I was looking for a way of visualizing the association between different categorical variables (nominal and ordinal variables). Since a heatmap will probably not work for categorical variables I think that a correspondence analysis should be a good option. Is it ok to include nominal (more than two levels) and also ordinal variables together in a correspondence analysis? I would greatly appreciate your feedback!

Dear SAS Community, I would like to know if there is an association between a nominal variable 'Ethnicity' (8 unordered levels) and an ordinal variable 'Overall1 ' (9 ordered levels) which means overall acceptance. In other words, if there is an influence of the Ethnicity of the consumer in the overall acceptance of the fruit that is presented to the consumer. If I try proc freq with the chisq option I get the following table: proc freq data=one; tables Ethnicity*Overall1 /chisq; run; Statistic DF Value Prob Chi-Square 40 48.3949 0.1702 Likelihood Ratio Chi-Square 40 50.1632 0.1302 Mantel-Haenszel Chi-Square 1 0.4461 0.5042 Phi Coefficient 0.1349 Contingency Coefficient 0.1337 Cramer's V 0.0603 WARNING: 37% of the cells have expected counts less than 5. Chi-Square may not be a valid test. Which statistic test should I use to see if there is an association between these two variables? I would greatly appreciate your response!

hi, i try with a flow to insert rows. First, I create a table (APPEND) and after, a seconde table (APPEND_NEW) with the same column. It's a very simple case but it's to understand because it can be very helpful and I don't want to use program. But, I have this error. The flow say : An error occurred while the system was executing the ‘Flux.flw’ flow. The ‘Insert rows’ node has no matching columns between the source and the target How can I fix it? thanks for your help

Beyond predictive accuracy, modelers care about stability—which variables are selected and whether the parameter estimates remain consistent across different samples of the data. In my previous post, Improving Predictive Accuracy: FCP vs LASSO in Regression Modeling, I showed that folded concave penalized (FCP) selection outperformed LASSO on the PVA_Donors dataset (available in SAS Viya for Learners). In this follow up, I shift the focus from accuracy to stability, using 5‑fold cross‑validation to compare how often each variable is selected and how much the parameter estimates vary under FCP and LASSO. Compared to LASSO, FCP yielded greater variability in coefficients while selecting more variables overall. So relative to parameter estimates, LASSO is more stable while FCP provides slightly better predictive accuracy on this PVA_Donors dataset.
