Theminpack.lm(...)function in packageminpackuses the exceptionally robust Levenberg-Marquardt algorithm for non-linear least squares estimation. In fact, the paper you cite mentions L-M specifically. The problem withminpack.lm(...)is that it is much more difficult to use (you have to defin...
I am trying to regress RET on mktrf, smb and hml for each stock (ret1 , ret2 , ret3 etc.) I'm new to R, this is my best shot at what I'm trying to accomplish: df<-read.csv("stockRetFF.csv",header=TRUE,sep=",")i<-1 j<-2 k<-3 l<-4 lm_results<-list()while(i<...
Summary: R linear regression uses the lm() function to create a regression model given some formula, in the form of Y~X+X2. To look at the model, you use the summary() function. To analyze the residuals, you pull out the $resid variable from your new model. Residuals are the ...
description and/or gene function with a model score > 0.2. For these 229 proteins, we carried the predictions made by ProtNLM over to our functional annotation. Additionally, 14 microsporidia-specific gene functions were predicted with high confidence by our approach but were not recognized by...
the mean square error of the network running of the validation set was calculated. Then, the neurons will apply a specific linear function in the hidden layer and a specific linear function in a hidden layer to collect the linear combination and bias. Finally, the output data will give the ...
Where is the "Search on this page" function gone to ? Anonymous September 15, 2010 @Microsoft: Where is IE9 installed??? I cannot see an icon on the desktop and I see no 'Internet Explorer 9" in the Start Menu?!?! :( :( Anonymous Septe...
1, 2 Obvious ethical implications of experimentally decreasing adult neurogenesis in humans makes human studies on the function of neurogenesis impossible. However, the antimitotic mechanisms of many of the life-saving chemotherapy treatments for cancer have the likely side effect that they decrease ...
resultr = lm(returnapple ~ returnsandp) summary(resultr) It cannot get any more simple than that, but for some reason, I get the error above. I checked that the length of returnapple & returnsandp is exactly the same. So what on earth is going on, please?

Studies of gain-of-function or loss-of-function in C2C12 cells have shown that NEAT1 promotes myoblast proliferation but inhibits myoblast differentiation and fusion [22]. NEAT1 is downregulated in acute promyelocytic leukemia, where it promotes leucocyte differentiation [23, 24]. The results show ...
