Apologies for the elementary nature of the question (yes, I'm another newbie)... I'd like to perform a multiple regression on a single data set containing a representation of energy consumption and temperatures containing account number, usage (KWh), heating degree days (HDD) and cooling degree (CDD) days. I want to get the coefficients back from the following equation: lm(AvgKWh ~ AvgHDD + AvgCDD, data=usage) Given that the data set contains the usage of different accounts (e.g. some large energy users and some small energy users) I...

Hello, I am trying to do a logistic regression and have one predictor variable (x) that is ratio and two predictor variables (y and z) that are categorical. These have three levels each which I have called "High", "Medium" and "Low". My question: do I need to use a numerical coding scheme for the categorical variables as required by some statistical software

Hello all, I'm new here and I'm interested in building a small PBX with asterisk at home. I have one single PSTN line and ethernet cabling in place. I already have fairly decent PC that I can use (AMD FX 8350 16GB of RAM and RAID 10 SATA disks). I make and receive 10 calls a day on average. I want 4 IP phones connected to the ethernet network. When there is a incoming call, all

Hi everybody, somehow i dont get the shapiro wilk test for normality. i just can?t find what the H0 is . i tried : shapiro.test(rnorm(5000)) Shapiro-Wilk normality test data: rnorm(5000) W = 0.9997, p-value = 0.6205 If normality is the H0, the test says it?s probably not normal, doesn ?t it ? 5000 is the biggest n allowed by the test... are there any other test ? ( i know qqnorm

...k because that affects the expected energy draw of the server. If it?s old, it could be 200 W or so. If you?re using ?old? rather loosely, then it could be down in the double digits. Here?s why it matters: https://www.rapidtables.com/calc/electric/energy-cost-calculator.html At 12 pence per kWh ? typical for power in some places in your country, based on your TLD ? it?s going to cost you about 1 pound per watt consumed if it runs all day every day. If it draws 35 W, that?s ?35/yr. If it draws 200 W, that?s ?200/yr. If the cost is high enough, then it?s probably cheaper to buy a new ene...

Hi there, I've used R before, but I just got a new computer with Leopard and I'm having trouble installing.

I've spent several hours trying to track the answer down myself and failed miserably so a simple question for everyone that will no doubt have a painfully obvious answer. What's the command to calculate the critical value of r using a two tailed test with a given alpha and degrees of freedom? I.e., alpha=0.05, df=18, two-tailed test, with the result being 0.4438 -- View this message in

Hi All, I'm fitting a Poisson regression. And I want to plot 95% Confidence Interval of Regression Estimates. After coming back to original scale (using following formula): exponential(estimate +/- 1.96*SE), at best I can get the output in the form of estimates, lower_limit, upper_limit values. As far I know forest() in metafor package needs input in the form of estimates and their

Dear Sir I am Amit Nirmalkar, M. Sc. Statistics. I generally use SPSS package for analysis. I wanted to run Conditional Logistic Regression in SPSS but this technique is not available. So I thought of R s/w. I am totally blank about R. Can you please send me few of R. Also how to run Conditional Logistic Regression in R.
